Chen Wan'an Bubi blockchain

1. How to explain the concept of blockchain? The understanding of people in each instry is different, and the relevant explanations are graally emerging because of more and more practical applications. With the popularity of this blockchain technology, the relevant achievements are also growing. If we want to understand this kind of technology, we must have a deep understanding from the reality

in the past six months, the concept of blockchain has graally become hot in China, and the financial circle has been blowing waves of blockchain whirlwind. With its unique technical advantages, blockchain has attracted more and more attention and favor from people in the instry. With the characteristics of decentralization (or multi centralization), high transparency, impossibility of tampering and no single point of failure, blockchain technology is coming into the vision of financial institutions and enterprises. At least it has been applied from theoretical discussion to practical application in many fields, such as digital currency, payment and exchange, registration and settlement, digital assets, traceability and anti-counterfeiting, supply chain, Internet of things, etc

"blockchain" was first released in early 2009 as "bitcoin". Blockchain has become the basic protocol and technical application for the launch, recording and circulation of bitcoin. Although bitcoin has been controversial since it came into being, and it can not even be regarded as "currency" by the government and monetary authorities, the blockchain technology applied by bitcoin has been widely concerned by the government and monetary authorities

why has blockchain become a hot technology and topic

perhaps the most important of these is that bitcoin, which is based on blockchain technology, has opened a new technology and rule system exploration and attempt, which has little connection with traditional society (offline) and is completely applied to the online world (online), such as Internet users' identity verification, wealth confirmation, transaction records, notarization verification, etc, This provides people with an alternative path and unlimited reverie to adapt to the development of the Internet society
from the perspective of its application in bitcoin, blockchain intuitively means a new set of network block (block, also known as community) establishment, bitcoin configuration, netizen identity verification, and bitcoin (value) confirmation and transaction records formed by mining by combining encryption technology with Internet technology, As well as the extended encryption of bitcoin cross block flow (value transfer) (including factors such as block and transaction time identification) registration and verification, the internet protocol rules and ledger system including block chain, whole process encryption and mutual authentication. Because bitcoin is not a substitute for offline fiat money, but a new and decentralized network currency (virtual currency) issued and managed by the illegal monetary authority, which mainly imitates the mode of gold and is completely protected and supported by the Internet basic protocol and strict encryption technology, it has also formed a set of virtual currency which is different from It is also not subject to the new monetary rules and systems of social laws, and can be traded or exchanged with legal tender. Bitcoin has been more than eight years since it was launched, and there has been no record of funds or user information stolen. Its security has been verified, and its efficiency and cost of capital clearing also have obvious advantages. This makes people have more confidence in the blockchain technology applied by bitcoin, and it is also more and more clear that although blockchain is a technology and protocol initiated and applied by bitcoin, blockchain is not the same as bitcoin, and its application will never be limited to bitcoin. The application of blockchain can be decentralized or centralized; It can be public chain mode or private chain mode. Therefore, after bitcoin, blockchain technology is constantly developing and innovating, and constantly exploring new application fields, especially in the financial field

the reason why more and more people attach great importance to blockchain is that with the development and wide application of the Internet, more and more economic exchanges and trading activities have been transferred to the Internet, and the network world (or online society) is rapidly expanding, enriching and active, while online transactions must solve the problems of identity verification, value verification, transaction records, etc The efficiency and security protection of inspection and verification need strict intermediary and agreement (rules or constitution). In this regard, the traditional thinking and practice is to conform to the development track of the transfer from offline trading to online trading, and push the common rules and practices of the real (offline) society to the online (Network) society, but it is increasingly difficult to adapt to the needs of online trading in practice
for example, the natural choice of the party's identity verification is to add the account or transaction password, as well as biometrics such as Facebook, iris, fingerprint, etc., based on the information of the identity documents protected by the laws of various countries, to carry out the identity verification of online transactions. But this method, first of all, makes the citizenship information of the cross-border interconnected network world subject to the real social administrative jurisdiction, At the same time, non digital, multi identity information collection and verification will greatly increase the cost and rece the efficiency
moreover, in real society, all kinds of economic activities involving capital liquidation, except direct cash transactions, require the parties to open accounts in banks and other institutions first, and carry out capital liquidation through the account opening institutions. However, for various reasons, even in a country, it is impossible to require all citizens to open accounts in an account opening institution (including its branches), It is even more impossible to do this between multinational companies, which makes the transactions of the parties who open accounts in different institutions must be completed through the clearing between their account opening institutions. It will seriously affect the efficiency and cost of transaction confirmation and capital clearing if this mode is implemented in the network world

in addition, in real society, the valuation and liquidation of trading activities must involve money, which is legal tender protected by national or regional sovereignty. In the case of cross-border Internet Interconnection and cross-border development of Internet transactions, transaction pricing and capital clearing also involve currency issues. The operation of multiple currencies will greatly increase the cost and risk of clearing. Therefore, the development of network world and network transaction needs the innovation of identity verification, value verification, currency valuation, transaction confirmation and record, account management and verification. Bitcoin and blockchain technology provide very important enlightenment and practice

of course, blockchain is still a new concept and technology, which needs further verification and improvement; The application of bitcoin is also an extreme example: the initial bitcoin can not be directly converted from legal tender, but can only be obtained through "mining" in the network world. Therefore, bitcoin can completely set aside the offline social rules, form a new set of game rules by using blockchain technology, and extend from online to offline. In real society, whether online or offline transactions, the main body is people (including legal persons). The management of their wealth or value should not be completely divided into two worlds, but must be connected and integrated. Therefore, o2o is necessary. This requires the application of blockchain not only to study and solve the problems of the network world, but also to study and solve the connection and integration between the network world and the real society. This will bring more challenges and risks, and also require more people, more strength, more in-depth discussion and innovation. It is also possible that blockchain technology will be replaced by more advanced and perfect technology in the future, but the historical value of blockchain will be indelible

the development of blockchain technology in China

Bubi blockchain is a commercial blockchain. Bubi covers seven areas: exchange, points (multiple points, gege points), insurance (sunshine insurance will launch accident insurance on our blockchain in a month, which can greatly rece channel costs), equity crowdfunding (gold stock chain, etc.), supply chain finance (Qian Xiang, etc.), supply chain (cooperation with the material chain, etc.), jewelry anti-counterfeiting, etc. Some funds cooperating with Bubby have committed 150 million investment funds. Bubby plays the role of "LP" in the fund, helping the fund identify and invest in companies related to blockchain. At present, the average amount of angel investment obtained through Bubi blockchain is about 3 million, with an average valuation of more than 40 million

blockchain can drive the birth of a new business model

the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. For example, in the Internet of things instry, some organizations have proposed to use blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of things devices. Using blockchain technology, IOT equipment manufacturers can greatly extend the life cycle of procts and rece the cost of IOT maintenance

blockchain technology has a flexible architecture

according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions<

blockchain technology is a useful tool to realize sharing finance

the essence of sharing finance is to realize the optimal allocation of financial resources by recing the asymmetry of financial information, and to ensure the implementation of the rights and interests of both parties in the transaction and facilitate the transaction through strict third-party authentication and supervision mechanism. Through the use of blockchain technology, financial information and financial value can be more strictly protected, and more efficient and lower cost flow can be realized, so as to realize the sharing of value and information

"from the perspective of historical development trend, money has always evolved with the development of technological progress and economic activities. From the early physical money, commodity money to the later credit money, it is a natural choice to adapt to the development of human commercial society. As the currency of the previous generation, paper money has low technology content. From the perspective of safety and cost, it is the general trend to be replaced by new technology and new procts. It will take at least 10 years for China to implement digital currency, so digital currency and cash will be in parallel and graally replaced for quite a long time. "“ For digital currency, blockchain technology is an optional technology, which is characterized by distributed bookkeeping, non account based and non tampering. If digital currency focuses on the protection of personal privacy, blockchain technology can be selected. The people's Bank of China has deployed an important force to study and discuss blockchain application technology. However, so far, blockchain still occupies too many resources, whether it is computing resources or storage resources, which can not cope with the current transaction scale. Whether it can be solved in the future depends on the situation. "

the development of Internet is in the ascendant and irreversible. The development of the network world and its connection and integration with the real society are also the general trend, and the corresponding rules and technology are of great significance. China has been in the forefront of the world in Internet application, and should actively explore and contribute to new rule making and technology application, and strive to lead the new development of the Internet world

what is the concept of blockchain? People will realize that blockchain technology plays a more and more important role in reality, and is supported by many organizations, so that the popularization of blockchain in reality has entered a new application stage.

2. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

3. As a rookie of Bubi blockchain, I'll tell you
Application of blockchain technology in banking

2.1 self regulatory platform

we rarely see a platform that can conct self-regulation without intervention. In all areas similar to the financial instry, central banks and regulators (such as the securities and Exchange Commission) come to set uniform rules and manage them. Blockchain technology makes the system no longer need the supervision from enterprises or government entities, so as to regulate the operation of the system. Blockchain provides a mechanism called "workload proof", which allows each computer node in the system to participate in the approval of each transaction. The system has built-in check and balance mechanism to ensure that no computer in the system can deceive the system. All of these reviews and supervisions are completely automated by the computer. At present, there are many other consensus models that can replace the "workload proof" mechanism, but still retain the core idea that each client or node can manage the system point-to-point. What's more, blockchain makes every element in the system completely transparent. Therefore, for such a large-scale community all over the world, blockchain technology can easily review and manage it - "supervision from the public", thus effectively recing fraud. Imagine how much it can save costs and improve efficiency

2.2 compliance with the law and easy tracking

actors (users) and their behaviors (sending money or assets to others) are recorded on the blockchain. Any transaction between the two parties can be tracked and inquired, and can be proved in court. This is because all transactions need a set of public key / private key to encrypt and decrypt processing and transactions. Once they are added to the blockchain, they are permanent and unchangeable. Any record, once written to the blockchain, cannot be tampered with. Anyone holding assets or digital currency on the blockchain will have their own public key on the blockchain. When a transaction occurs, it needs to be signed by the previous holder who controls these assets using the private key. Blockchain also allows a variety of mechanisms for transactions. For example, it can be set to require two people to jointly sign a transaction. In a system without endorsement of enterprises or government, the legally binding mechanism can greatly enhance the trust factor for the system

2.3 built in business continuity

a global platform can not bear the risk of downtime when concting major transactions. Blockchain, a complete point-to-point network, has many distributed nodes and computer servers to support, which has high reliability. Every node in the system keeps a of the complete blockchain data. This makes the whole network highly fault-tolerant, if any part of a few nodes have problems, it will not affect the other parts of the network continue to operate. This makes it possible to achieve 24 / 7 all-weather operation characteristics like disaster recovery center or database rendancy center without using complex technology

2.4 evolution model without burden

in the system, there are a series of rules and key points to help decide who has the right to approve the transaction and what needs to be reviewed before the transaction is written into the blockchain. Blockchain technology can fork out new versions according to different environments and business model requirements. The new version also needs to conform to the overall concept of blockchain. All these changes must be approved by all members of the system, and everyone can get the same benefits. In addition, these changes will not affect the transactions that have occurred and confirmed on the blockchain. For a system, it has enough robustness and flexibility. People often compare the similarities between the Internet and blockchain, including their growth potential and business prospects. These two systems have very similar characteristics. The Internet does not need or does not have a centralized management department (except for a few for the management of agreed URL and domain name registration), but also has enough rendancy and strong fault tolerance. The Internet has been developing for so many years, from basic text to rich graphics, video, animation, and all this has not affected other existing systems and content. Blockchain has fully proved its function and practicability in bitcoin system. Just as the famous Chinese philosopher Lao Tzu said, "the tree that embraces is born at the end of a tree."; The platform of nine layers starts from the base soil; A journey of a thousand miles begins with a single step. " I think this should be the creed of all the pioneers of blockchain technology
as a rookie of Bubi blockchain, I tell you so much!

4. Recently, the principle of blockchain has been talked about by many people. Obviously, blockchain has been deified by many people. It seems that all walks of life can use blockchain technology. However, to some extent, it is like a black box. We all know that blockchain has many features and benefits, but we don't know how to do it. In fact, as long as you understand the principle of blockchain, you don't have to hesitate

blockchain is not a single innovative technology. Instead, it brings together many cross domain technologies, including cryptography, mathematics, algorithms and economic models. Combined with the point-to-point network relationship, it can establish trust effect by using mathematical basis, and become a decentralized system that can operate without mutual trust or relying on a single centralized organization, Bitcoin is the first set of P2P e-cash system built by using blockchain technology, which is used to realize a decentralized digital currency system and ensure transaction security and traceability

however, how does the blockchain work and what key technologies it contains make it known as the trust machine? How can a transaction be verified in a P2P network that does not trust each other without the traditional trust institutions (such as banks, stock exchanges, third-party institutions and other centralized institutions)

to understand the operation principle of blockchain, we can first distinguish between transaction and block. Here, we understand the operation principle of blockchain from the generation of a transaction in the blockchain to the completion of the verification process and illustrate a block, and further disassemble the five key technologies of blockchain, See how it can be based on zero trust, decentralized, traceable and non tamperable

viewing the operation process of blockchain from a transaction

in bitcoin blockchain, when a transaction is generated through a node or wallet, the transaction needs to be transmitted to other nodes for verification. The method is to encrypt the transaction data by digital signature and get a string of unique hash values representing the transaction by hash function, and then broadcast the hash values to other participating nodes in bitcoin blockchain network for verification<

generate a new transaction

when a new transaction is generated, it will be broadcast to other participating nodes in the blockchain network first

each node will put several new transactions into the block

each node will collect several unverified transaction hash values into the block, Each block can contain hundreds or thousands of transactions

decide who will verify these transactions

each node will calculate the workload proof to decide who can verify the transactions, and the node with the fastest calculation result will verify the transactions, which is the consensus approach

the node that has obtained the verification right will broadcast the block to all nodes

the node that completes the pow as soon as possible will broadcast its block to other nodes

each node will verify and connect with a new block

other nodes will confirm whether the transaction contained in the block is valid, and accept the block after confirming that it has not been repeatedly spent and has a valid digital signature, At this time, the block is officially connected to the blockchain, and the data can no longer be tampered with

transaction verification is completed

once all nodes accept the block, the block that has not finished the pow calculation before will be invalid, and each node will re-establish a block to continue the next POW calculation

it can be seen that the principle of blockchain is not complicated, and its wide application is natural. Many companies have achieved fruitful results in the process of applying blockchain principles to reality. Bubi company is a leading blockchain service provider in China. It has made many breakthroughs in blockchain technology platform, which can meet the scenario of tens of millions of users, and has the ability to quickly build upper application business. Bubi blockchain platform is divided into bubichain and Bubi application adapters.

5. Bumeng builds a free and open digital asset circulation platform with data as the core
1. Asset issuance

multi-party and multi asset issuance. Indivials and institutions can issue their own digital assets; Any digitized asset can be issued and circulated on the platform
2. Asset transfer
asset circulation has changed from the original single center control to social circulation. Any channel with resources can become a catalyst for asset circulation and promote circulation
3. Asset query
view the issuance and circulation status of assets in real time, and manage the asset data.

6. What is blockchain? Blockchain is a kind of distributed shared accounting technology. What it needs to do is to enable all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels, one is to do the underlying technology of blockchain; The second is to do the upper application of blockchain, that is, the transformation, optimization or innovative application based on blockchain. Blockchain is still in its infancy. Many people are discussing with me how to guarantee both rights and privacy. Of course, now they are just exploring, which means that the content of the whole network should be fair and clearly protected. That's all I can say. This is how I will arrange it in the future

blockchain concept? The idea of blockchain is to completely decentralize and rely on distributed justice. In that case, the cost will drop a lot in theory, proving that the real assets and property rights are directly corresponding on the Internet. After solving the problems of decentralization and asset ownership that the first generation of Internet information did not solve, how much role does big data play in financial innovation? Only by using big data to register can we know who it belongs to. In fact, this has always been a problem that we can't solve now. It's not a small problem. Any technology in the capital market that makes clear the property rights of things that are not clear about the property rights is a huge change for the whole market

what is a blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanism. There are still some problems that can not be completely solved. For a simple example, when it comes to user privacy, I have a data on the machine, and the partner comes and makes an insurance to analyze the cooperation. Here is a risk to be given or not to be given, whether it can be dealt with, or whether the property right of the laboratory can be clearly divided, and then the processing right and the data right can be clearly stated, It's common for all of us to proce common procts. We need to divide different things, how to price and how to divide them. In addition to the technology of blockchain, a distributed database, the above is a new task, which is another problem, and then the problem of pricing, which is the problem of market mechanism, which is proved and approved by all fields, So I think blockchain is a very good core technology, but it can't cover all the problems

Introction to Bubi blockchain

Bubi blockchain is mainly positioned to provide commercial level blockchain infrastructure services, mainly including building a blockchain system and building a supporting system with high scalability on the blockchain system. And the support system above is the application of all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, almost all the energy of the team of more than a dozen people has been devoted to the research and development of the underlying technology. The reason why Bubi blockchain chooses points has something to do with the promotion method of the market. As we all know, blockchain is a very suitable technology for digital asset issuance and trading. Integral is a kind of natural legal and compliant digital asset, which has little impact because of its small amount. So it's a very suitable choice to take points as the first attempt of digital asset issuance. Issuing points based on blockchain can also bring great help to the circulation and exchange of points

what is a blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to recing the cost of property transfer, blockchain technology can also be applied to various fields, such as company stocks, financial derivatives and points planning of commercial institutions. At present, blockchain community is focusing on promoting the wider application of this technology in the field of financial assets, and related platforms that are still under development have also received considerable investment

blockchain concept? In terms of structure or definition, these things are very different. The U.S. dollar, or any currency, by definition, is mainly used as a medium of transaction or a store of value for economic activities. Within the geographical scope of a certain currency circulation, people in the region reach a consensus on the use of this currency, which is convenient for people to use the same currency to purchase goods or services (the function of currency as a trading medium). We have the responsibility to manage money through monetary policy, so as to ensure the value of money and avoid inflation (the value storage function of money). In today's world, almost everyone uses some kind of currency in their daily life

what is a blockchain? Even developers in the blockchain community tend to ignore the grand picture mentioned above. There are many competitive projects in the blockchain community, which are also full of disputes about the evolution direction of blockchain technology. Over time, some projects in the community will succeed, others will not be so lucky. Things will not always develop in the direction we expected. However, no matter how these projects in the early blockchain community develop, it has been very clear that blockchain technology has brought us at least one revolutionary function: blockchain technology will greatly rece the cost of financial property transfer, and blockchain will be used to control Manage and distribute financial assets

what is a blockchain? Blockchain concept? After a certain application analysis, we will go back to the starting point. The definition of blockchain technology will become more and more abundant with the development of application. People will find more mysteries of blockchain technology.

7. The Qiang people's Valley in Wenchuan, dalab manor is fun. 15 kilometers away from Wenchuan County, there is a place known as the "Qiang Valley" and the birthplace of Shibi (the most authoritative cultural person and knowledge integrator among Qiang people), which is also a typical original ecological Qiang settlement. Zagunao River from the snow mountain records the history of this place. The rankou tribe of the ancient Qiang people once lived here, and it has been growing for thousands of years since then. Walking into the Qiang people's valley of Longxi, the Abbot's eaves are full of mountains and peaks, competing for wonders and beauty. The rich and colorful Qiang culture, such as mysterious and ancient Shibi culture, hand-made embroidery, Qiang blockhouses and Qiang characteristic dwellings, complement each other with the beautiful ecological and natural scenery. In recent years, Dongmen Village has developed 21 licensed farmhouses, one of which is Tang Chengji's. Tang Chengji, a native of Lianhe village in Longxi Township, once lived a rich life relying on the rich mineral resources (garnet, iron ore, marble, etc.)“ I used to mine. There are many ores on the mountain, and I made some money. Many people in our village used to mine. " Tang Chengji said, "it was found that the mining didn't last long, so we began to cultivate fruit trees in 2001. When it comes to tourism, we have to thank Hu Haiyun (leader of Zhanjiang's 2008 Wenchuan Longxi Township aid Working Group) of the 2008 aid construction working group for putting forward the instrial transformation, and we have just begun to graally turn to the development of tourism. " Wenchuan in 2009_ The people's government decided to build Longxi Qiang people's Valley, and tourists graally entered Dongmen Village. In June 2011, Tang Chengji's family seized the business opportunity and began to set up tourism reception“ At that time, there were only four rooms of my own for tourists. It was OK at ordinary times. I couldn't live on holidays like national day, so I arranged for them to live in other houses in the village. In June 2015, my family built a new house. There are 11 standard rooms upstairs, and the restaurant downstairs can accommodate 240 people at the same time. " Tang Chengji said with pride. Dalab manor. The park is divided into sightseeing area, cultural and leisure area, picking area and breeding area. In March, at the beginning of spring, a few peach blossoms are already very busy. I can't wait to express my gratitude for spring. Dalabu ecological economic manor covers an area of more than 60 mu, of which 30 mu is collective river beach land of United villages“ In the village, the 30 mu land is converted into 2 million yuan of shares. Dalab manor has 8% of the annual income, which is regarded as the village collective economy. In other words, our village has an annual income of 160000 yuan, which strengthens the collective economic development of our village. " Liu Sha, the first Secretary of Lianhe village in Longxi Township, said that dalab manor was mainly built by three returning party members with an investment of nearly 20 million yuan in the first phase. It is equipped with characteristic ecotourism sites such as Qiang cultural charm Experience Hall and greenhouse plantation. At present, it has been rated as the national intangible cultural heritage dalab Qiang new year transmission base, Qiang embroidery transmission base, sheepskin drum transmission base The demonstration base of entrepreneurship and employment for returning migrant workers in Wenchuan County and the demonstration base of rural tourism in Aba Prefecture.
