Chapter nine mining
in the general version, I use Germany more.
each has its own advantages.
to deal with American soldiers, we can use dogs, light tanks, air pilots,
American soldiers are used to train people.

2 when the lightning storm is launched, the upper left corner of the pointer cloud is aimed at the center of the base, so that the base can select the Red Army, then build a bull tank, use a mobilizer to fight the tank (until the last drop of blood is left), then pull the tank into the repair shop, and send a terrorist robot into the tank (be sure to be fast), When the tank is repaired, it will have the speed of a terror robot. Are you worried about winning<
4 airdrop buildings:
1. There must be paratroopers and the map must be fully illuminated< When the paratroopers are ready, build defensive buildings
3. After building the defense building, move the view to the place to be airdropped, left click the paratrooper, left click the built defense building, and then click the place to be airdropped on the map. If it is flat, it can be built. If it is not, left click the paratrooper, left click the built defense building, and then re cast
4. The success rate is more than 80%
5 at the beginning of the war, you will find that your base car has no change, but there will be several soldiers and an engineer around you. Then unfold the base vehicle and repeat the above process for many times, you will have a strong army
6 use China to occupy the Soviet base, build a replication center, surround the barracks with walls (no space), build Chinese soldiers, - 100 pieces, and get 1000 pieces after allowing soldiers to enter the replication center! 7. The super explosive vehicle uses Evan to hang bombs on five of its own soldiers, and then the five soldiers enter the air defense vehicle. In this way, the bombs will not explode in time, and the soldiers will be released when they find the opportunity. In this way, the five bombs will explode together, and the effect is greater than that of the nuclear car
8. Let the spy disguise as a dog, and the speed will be much faster than that of the ordinary soldiers, The enemy can't catch up even if they find it. If the enemy's dog comes after him and attacks the open space with force, as long as he is not hit by the enemy head-on, he can definitely escape
9 cheating code. You can get $10000 by typing "give me the money" in the game
10 the time and space soldiers will be invincible if they bump to the concave and convex points
11 as long as the "a" and "s" are pressed together, the proction of various houses in the construction column can be accelerated
12 when the money is almost used up, put the mouse on the headquarters, press l with the other hand, and the mouse will click quickly. The money is soaring, 260000! Suitable for encounter, online did not try, estimated also to
13F tracks the selected team, y tracks the third level goods in the selected team, and u tracks the critical goods in the selected team
14 first, the Soviet army was used to build barracks and replication centers. Then use a wall to surround the barracks and build troops. In this way, you will find that the replication center will send troops without any dection, In this way, we can build an infinite army

In the game of war, it is the same. If the use of troops is not to the point, although the war is won, it is not long, but lucky to win, There is a saying: it's better to teach him to fish than to give him fish. Because it's dead to take advantage of other people's tactics, but people are alive, so in this paper, the author not only tells you his own experience, but also takes pains to explain the reason. I hope you can understand the tactics created after a comprehensive understanding, so that you can have your own style & you can use them freely, and you can always defeat them after accumulating experience
if you don't understand the meaning of it, you can only bully those who are not of high standard by using the ready-made steps instead of using them flexibly, and you will be seen through a few times when you meet the experts, right
all of the contents have their own priorities to understand. Let's read them slowly and hope that they will become & quot; Red alert & quot; If you have any questions or think about it; To make complaints about " The so-called strategy is the overall plan of a war, and the policy it decides can often determine its victory or defeat. In a word, it is to guide our army to the most favorable situation.
1. How to develop economy, attack and defend (scissors, stone, cloth), and how to choose between the fish and the bear's paw, Therefore, we should not rely on the enemy not to attack, It's better to rely on your own strong strength to deal with it.
A. although it will be better to develop the economy with all your strength at the beginning, you can't be completely unprepared. In case the enemy uses the fast attack, it's not over.
B. If you start the fast attack when there is only one tramcar at the beginning, and in case the opponent doesn't defend with all his life, you won't be able to win the war What about being pressed back
C. if at the beginning you were afraid that others would attack you quickly and shut yourself up, and the enemy ignored you to continue to develop his economy, what would you do if you were shut down in the toilet? How to choose between them is very simple. Please see 3. Situation
2. Economy
Sun Tzu said: win the army first, win the war. That is to say, before fighting, we should first prepare the combat power to the advantage, and then fight the war. In this way, it's not easy to win. How can we prepare to be better than the enemy in redalert? In short, there are more troops than others. How can we get there? How can money come to mine; The answer came out: to dig faster than others, more proction lines, more troops = more chips on the battlefield, it's easier to win. In short, if there are more mines, it's also more natural. Pay attention to the AI of the mining vehicle is the upper left corner of the nearest area to the mine. In RA, pay attention to the fact that the mine should be built as close to the mine as possible If you pay attention to this point, the other side will win more if they don't have as many harvesters as you. The actual practice will be described later in the actual combat chapter. Therefore, how to use various methods to build the mine closer to the mine is the topic
although the more money, the better, but if they don't effectively convert the money into weapon units, it won't be used, so the more money the harvester For a long time, the relative weapon factories need to increase their proction to avoid waste. For example, except at the beginning, the money in the future should not exceed $4000. If it exceeds $4000, you will not spend enough money. The money you dig should be spent as soon as possible to maintain the guiding principle of digging first, buying first, fighting first, winning first.
3 Do you worry about the wrong development of information? Wide field of vision (Intelligence), sharp sense (observing the enemy's movement), quick response (quick judgment) are necessary for a good general (Intelligence). Whenever you want to know the dynamic strength of the whole field, the enemy's mining route is there, the simplest way is to build radar, and from time to time find some small soldiers to walk around and draw maps. It's more convenient to play with the Allied high-tech satellite With complete intelligence, the enemy's troops will naturally know what the enemy wants to do if they have unusual assembly or movement? The enemy's combat target (Ps. refer to tactics Chapter 1. Results)
(quick judgment) after knowing what the enemy is going to do, of course, we need to re deploy our building development mode again, otherwise it may be too late to re deploy when the enemy is killed, and it may be subject to people everywhere
but in a chaotic situation, how to judge the situation of the enemy and ourselves depends on experience
* in the game After the mid-term, in addition to operating the current operations, we need to constantly estimate the development status of the enemy and ourselves, the proction status of the enemy and ourselves. If our side has the advantage, we can continue according to the current mode. If the enemy has the advantage, we need to immediately re-establish a new operational policy (Sun Tzu said: when the situation is stable, it will stop, As the saying goes, early detection and early treatment will be impossible until the end of cancer (the gap is large).
4. Secret and spy prevention
the key point here is not to prevent some useless cases: intelligence personnel (because I assume that those things are not practical) also talk about the importance of intelligence in the front. If both sides are equal in tactics, the radar area is better This point is particularly important in the prelude. In addition to our active search for enemies, we should also encircle each other's search for enemies. If players really have no spare space, I will provide a simple method for you to refer to. If you put some infantry (press g) on the main roads leading to our headquarters, you can simply kill people and kill people.
strategically, if it is equivalent to the so-called strong one in tactics, it's just a matter of time It's to hide its weakness skillfully, not without it. For example, even if our headquarters is empty, the enemy doesn't attack because of lack of intelligence. So it's very important to gain an advantage in the intelligence war.
5 In my experience (except for special map), the army, Navy, air force, especially the air force are the most useless, unless you have enough money to play or have a comprehensive advantage
why? Because in redalert, all kinds of air forces can't fight the Navy against the ground forces (moving things), as long as they have a $1000 destroyer, how many air forces will be enough
the purpose of becoming an air force is that it can only be used to attack the enemy's buildings (for strategic use), but it will cost at least $10000 to build a Ko air force against the enemy's buildings. You think that $10000 tanks can buy a dozen of them
if the strength of the two armies is between Bozhong and Bozhong, if you see that the opposite side has bought an air force, you can laugh (you can win) how to win? The reason is that if the people who buy the air force don't succeed in attacking more than 2 times, it won't be worthwhile. Besides, the author has a set of measures to deal with the actual practice, which will be solved for you later in the actual combat chapter. As long as you know that the air force is useless, please don't buy it.
* for the Navy, if you play with the Soviet Union, I can also advise you not to buy submarines, because submarines will float when they launch torpedoes When it floats up, any tragedy will happen^_^ Those who play with the Soviet Union should take advantage of its relatively large tanks to win the main battle on land. If the map is dominated by seizing sea power, it should take destroyers as the main force, because in a ship to ship el, the strongest destroyer (and not afraid of the air force) cruiser, a 2000 destroyer and a 1000 4 destroyer, will win two cruisers (if you don't believe it, you can test it yourself)
mining proction cost is the total expenditure in the form of currency in the process of proction and sales of mineral procts. Mine proction cost is a comprehensive index reflecting the whole work quality of mining enterprises. Labor proctivity, mining plan, material consumption, equipment utilization and enterprise management level are all reflected in the proction cost. The composition of mining proction cost is complex. In order to facilitate cost management and analysis, proction cost should be classified< According to this classification method, the mining proction cost consists of the following items:
(1) auxiliary material cost. It refers to the cost of all auxiliary materials directly used for proction. It includes explosive, detonator, fuse, detonating wire, drill steel, cemented carbide, steel wire rope, wood, tire, cone bit, crusher liner, etc< (2) fuel and power costs. It refers to all kinds of fuel and power consumption directly used in proction. Including electricity, diesel, gasoline, etc
(3) wages of proction workers. It refers to the basic wage and additional wage paid to proction workers. The latter refers to various allowances and health care costs
(4) wage surcharges for proction workers. Including labor insurance, medical and health, welfare and other expenses
(5) workshop expenses. It refers to all kinds of expenses occurred in the workshop, serving the proction process and related to the workshop management. It includes:
A. funds needed to maintain simple reproction (abbreviated as maintenance cost). It is the cost source of cutting excavation (Development), proction exploration, equipment renewal and so on, which must be carried out in the continuous proction of mining enterprises. After using the maintenance cost, the proction mine no longer draws the depreciation cost, but in the design technical scheme comparison, the depreciation cost is still used to calculate the cost
B. maintenance cost. It refers to the expenses required for the daily repair and maintenance of fixed assets (Construction Engineering and equipment, etc.). Including maintenance workers' wages and maintenance materials
C. workshop management fee. Refers to the workshop in the organization and management of various management costs in the proction process. Including workshop management staff wages, wage surcharges, workshop office costs, water and electricity costs and laboratory costs< (6) enterprise management fee. It refers to the enterprise wide management and business expenses. It includes the salary of enterprise management personnel, wage surcharges, office expenses, travel expenses, warehouse management expenses, experimental research expenses, public utility expenses (water, electricity, etc.) and equipment depreciation and maintenance expenses related to administrative facilities and enterprise management
(7) sales expenses. It refers to all expenses incurred in the sales of mineral procts. Including transportation costs, sales personnel training costs, advertising costs, sales handling equipment repair and maintenance costs< (8) taxes and interest. It refers to all kinds of taxes and loan interest collected by the state and local governments. In the comparison of design schemes and other calculations, the concept of annual operating cost is often used, which is equal to the proction cost minus the depreciation cost< According to the relationship between cost and proction, direct cost refers to the expenses directly used in the proction process. The total direct cost of a certain period (such as a year) changes with the change of output, and increases in direct proportion to the increase of output, so the direct cost is also called variable cost. Although the total direct cost varies with the output, the direct cost per unit proct is basically constant within a certain range of output. Therefore, the direct cost is often in yuan / ton of proct
indirect cost: refers to various expenses that are not directly related to the proction process and serve the proction process. In a certain period, the total amount of indirect cost is basically constant, so indirect cost is also called fixed cost. Although the total amount does not change with the output within a certain range of output, the indirect cost allocated to the unit proct decreases with the increase of output. Therefore, the indirect cost is often in yuan / year< (1) raw materials and auxiliary materials: the raw materials for mining work are ore bodies, the value of which is not included in the mining cost, and the raw materials for mineral processing cost are raw ores. Auxiliary materials refer to explosives, detonators, fuse, detonating cord, drill steel, pit wood, cemented carbide and other materials used in mining, mining, crushing, ventilation, drainage, filling and other links. The calculation adopts the local unit price multiplied by the unit consumption. In case of outsourcing, the transportation and miscellaneous expenses shall be considered
(2) power and fuel cost: power and fuel cost refers to the cost of electricity, compressed air, gasoline, diesel and kerosene consumed in the proction process. The unit power consumption is determined by the power and working time of the equipment, and the price is calculated according to the current national regulations. Fuel cost is determined by multiplying unit price by unit consumption
(3) wages and surcharges of proction workers: wages and surcharges of proction workers refer to the wages of direct proction workers and auxiliary personnel (excluding machine repair and non proction workers) engaged in mine proction and the enterprise benefits drawn according to a certain proportion of the total wages according to the state regulations. The basic wages of proction workers in enterprises can be selected according to similar enterprises and local conditions.

Xihua mountain, 9 kilometers northwest of Dayu County, is rich in tungsten resources, known as the "tungsten capital of the world"
Dayu tungsten has been discovered and mined for more than 100 years. As early as 1882, Wu Liheng, the German priest of Dayu Evangelical Church in the name of preaching, discovered Wujin in Xihua mountain, bought the monk's garden of Qingyun temple in Xihua mountain, and smuggled tungsten for export. The underground treasure of the Chinese nation is not allowed to be plundered by imperialism, and most of the people rise up to fight. In 1901, a mass movement against foreign religion led by Chen Damao broke out in Dayu, burning Meiling church. However, the struggle was suppressed and Chen Damao was killed. The people of Dayu, who are full of patriotism, are not afraid of violence and go on one after another. In 1908 (the 34th year of the reign of Emperor Guangxu), at the strong request of the people of Dayu, Yu Mingzhen, the governor of Jiangxi Province of the Qing Dynasty, negotiated with Wu Liheng, the German priest, and the German organization in China for many times. Under the powerful offensive of our party's awe inspiring righteousness and the overwhelming indignation of the broad masses, he took back the right to mount Xihua at one stroke
before liberation, tungsten mining always remained in the primitive backward situation of workers' sledgehammer and ignition and blasting, and dilapidated small civilian kilns were all over the mining areas in the region. After the founding of the people's Republic of China, the state attached great importance to the development of nonferrous metallurgy instry with tungsten ore as the main body. Among the Wuling mountains in Wanyan, Xihuashan mine is one of the 156 projects aided by the former Soviet Union and listed as the key project of the first five year plan of the state. The spring breeze of socialist construction has made a hundred year old mine full of youth and great changes. However, half a century later, the world-famous tungsten capital is still shrouded in the semi colonial cloud of exporting tungsten ore and importing tungsten wire. The transportation of high-quality tungsten sand by truck, across the sea, and flowing to the western instrial countries, in exchange for the humiliation of tungsten procts that have appreciated dozens to hundreds of times, has hurt the Chinese descendants and the people of the tungsten capital< In 1969, Premier Zhou Enlai clearly pointed out at a meeting that China should reverse the situation of tungsten sand export and tungsten wire import. The spring tide of reform and opening up has made the people of tungsten realize the will of the premier. The people of Dayu have completed a full range of technological transformation from ore smelting to tungsten wire proction. The wolframite concentrate proced by Dayu has won the national silver award, the Scheelite Concentrate has won the National Gold Award, and the annual output of 500 million meters of tungsten wire has flowed to the international market, After deep processing, ammonium paratungstate and blue tungsten (blue tungsten oxide) have opened the door of many countries. As early as the Song Dynasty (960-1279 A.D.), tin mining began in the areas of Guanyinyan, dashuikeng, zhengqiaotou and niupokeng in Xihuashan. It did not stop until the reign of Emperor Kangxi of the Qing Dynasty (1662-1723 A.D.). At that time, although black stone can be seen everywhere, it is not known that it is tungsten ore. In the late Qing Dynasty (about 1906), in the midsummer, Wu Liheng, a German priest of Catholic Evangelical Church in Dayu County, went up Xihua mountain in a sedan chair along the winding and rugged path in order to seek seclusion. After walking to see the exquisitely constructed Qingyun temple and enjoying the natural scenery, Wu Liheng found that all the places he went were black and shiny stones. Wu Liheng was very surprised. He picked one and weighed it. He realized that it was a kind of precious mineral. So he picked several pieces and took them back to the church. In 1907, Wu Liheng returned home with the ore. after identification, it was found that the ore contained tungsten, a rare metal
then, in order to develop the arms instry, the German imperialists ordered Wu Liheng to rush back to Dayu. As soon as he could, he could not get more tungsten ores back to Germany. When Wu Liheng returned to Dayu, he secretly sent the believers to the mountain to pick them up in the name of building gardens and bought them at a low price. Then hire a porter, pick to Nanxiong County, Guangdong Province, shipment through Guangzhou, Hong Kong, shipped back to Germany
soon, in order to monopolize the tungsten resources, Wu Liheng privately mined the tungsten resources and bought the mountain right from the monk Miaoyuan of Qingyun temple in Xihua mountain with 500 silver yuan behind the back of the local government. In this way, Wu Liheng began to plunder the ore openly< In the winter of the 34th year of the reign of Emperor Guangxu, a student of Dayu nationality who was studying in Xijiang excellent school (former Central University) in Nanjing also brought Xihuashan ore to the laboratory of the school for identification, and then he knew that it contained rare metal tungsten. At this time, Yu Mingzhen came to Dayu to inspect Nan'an, Ganzhou, Ji'an and Ning Daotai. He learned that Xihuashan proced tungsten ore and that Shanquan was sold. He ordered the county government to take back the ore. After many negotiations with Wu Liheng, he redeemed Shanquan with 1000 silver yuan. Since then, the glorious history of "tungsten city" has been opened. During the period of civilian mining
when a tungsten mine was first discovered in Xihua mountain, there were exposed tungsten ores everywhere on the mountain. Catholics in Evangelical Church could pick up dozens of Jin a day, some as much as 100 Jin. After the redemption of the mountain right, it will be taken by the local people< In 1914, after the outbreak of the first World War, the arms instry of various countries urgently needed tungsten to make ordnance. The imperialists of the United States, Britain and Germany sent their agents to Dayu county to buy tungsten sand. Suddenly, the price of sand soared, which attracted thousands of farmers in Dayu county and neighboring counties to pick up and dig mines. At that time, most of the peasants did not live in the mountains for a long time. They only brought a little grain, simple cooking utensils and tools, lived in the open air and g tungsten sand. The peasants go up and down the mountain from one place to another without any restriction
in the seventh year of the Republic of China, there were more than 20000 migrant workers in Huoyu, Nankang, Shangyou, Chongyi, Xinfeng and other counties on the mountain. There were many sheds on the mountain, shops everywhere, and the output of tungsten sand also increased greatly, which was the peak period since the mountain was founded. At this time, migrant workers use the flushing port to wash the coarse sand to improve the purity of tungsten sand. In the case of tungsten ore trading, the collector will purchase the tungsten ore if he considers that the tungsten ore is up to the standard. The price of tungsten sand is 15 yuan per 100 catties
in the 8th year of the Republic of China, a group of migrant workers from Shuikoushan, Hunan Province came to Xihua mountain. They used steel drill and black nitrate blasting to excavate not only along the vein, but also small holes, which pushed the mining technology of Xihuashan forward. Due to the improvement of mining technology, the output of tungsten sand increased day by day, and tin sand was re listed in the market in the decade of the Republic of China, the price of tungsten sand suddenly dropped to 10 yuan per 100 catties
in the 11th year of the Republic of China, with the support of the US, British and German imperialism, miners from all over the country came to Dayu county to set up sand collecting companies. Among them, there are more than ten companies, such as "Huaji", "Ruiji", "deyuyuan", "Huanan", "Yongsheng", "Yuehua", "guangjuan" and "Huanji". The purchase of tungsten tin sand began to be priced according to the degree. There are hawkers on the mountain to buy, tungsten sand price per 100 catties, the highest is 14 yuan 8 cents, the lowest is 13 yuan; Tin sand per Dan (105 Jin) price is 40 yuan to 54 yuan. After the peddler collected the sand, he hired a porter to pick it up in Dayu county and resell it to the sand collecting companies. The cost for each load (125 kg) was 5 millicents. The price of tungsten sand in Dayu county is 15 yuan and 5 cents per 100 Jin. The price of tin sand is 55 yuan per 100 kg, so the migrant workers often sell the tungsten tin sand in Dayu county
in the 12th year of the Republic of China, after a certain army of Guangxi stationed in Dayu, they were arrested, sent to donate money and robbed wantonly, and migrant workers in the mountains went home to escape. There was once a "cold mountain" in Xihua mountain. The sand collecting companies in Dayu County closed down because they could not receive tungsten sand. In the 13th year of the Republic of China, after the Guangxi army left Dayu, the mountain returned to normal
with the deepening of mining and the increase of difficulty, in the 16th year of the Republic of China, a proction group - "shed", which was composed of several or dozens of migrant workers, began to appear on the mountain. There are four types of shed owners: one is family style, with parents as the shed owners. Some of the other members of the family go into the hole to mine ore, some break ore, and some mine. Second, in the form of joint-stock, the migrant workers are free to combine, and the board expenses are shared equally, and the income from selling sand is shared equally. The third is the type of shed owner. One is a person who is the shed owner and employs several people. Employees are only paid (employees are paid 2 to 4 millicents a day) or part of the net income. The amount of wages depends on the working skills, the food is provided by the shed owner, and the mining profits and losses are all owned by the shed owner; The other is that one person is the owner of the shed, and several people are employed to provide food without pay. When the surplus is made, the owner will get half of the money for selling sand, and the employees will get half of the money for selling sand. When the deficit is made, the owner will lose the food expenses of the whole shed, and the employees will lose the labor force. The fourth is the payment of sheds. The food, utensils, explosives and other expenses of the migrant workers are loaned by the peddlers, merchants or gentry. The proceeds from the sale of sand will be repaid first, and the remaining two tenths of the loan will be paid by the lender, and then the migrant workers will share equally. All in all, except family style, the rest of the mountain has great liquidity, and migrant workers can choose sheds and become shareholders at will without interference. Hawkers go to the mountain to buy tungsten sand and weigh 15 Jin for every 100 Jin. The price is one yuan less than that of Dayu county. Due to blind and chaotic mining, heavy casualties and disputes were caused, and fights often occurred. The migrant workers were naturally divided into factions. At that time, there were mainly Jiangxi faction headed by Yan Zheng and Hunan faction headed by Jiang Guoyu< In order to raise construction funds, the Department of construction of Jiangxi provincial government began to levy tungsten sand tax in the 17 years of the Republic of China. In Dayu County, seven sand collecting companies, including guangju'an, a Guangdong businessman, jointly formed "Liji" company to undertake the agency transportation and marketing of tungsten sand and pay the tungsten sand tax uniformly
in the 18th year of the Republic of China, more than a dozen sand collecting companies in Dayu county jointly formed the Dayu tungsten sand trade association to purchase tungsten sand. As the price of sand was too low, the Xihuashan branch of the Communist Party of China organized and led the workers in Xihuashan, Dangping and hongshuizhai to hold a general strike against "arranged", forcing the government to dissolve the "Dayu tungsten sand trade association" and cancel the private agent marketing. In the same year, most of the mountains in Xihua mountain were classified as "official land". Migrant workers are not subject to any interference in the mining of "official land", and the government does not put it on record, nor does it have any reference. The holes opened by the migrant workers in the "official land" belong to the owner, or they can be rented, and no one else can occupy them. But there are still a few mountain areas that are still privately owned, such as shipingli, dashuikeng, zhengqiaotou and guoshangnao. No matter whether they are "official land" or private areas, there is basically no mountain rent. Only shipingli, a private area, charges low mountain rent, ranging from 1 to 5 millicents per day
in the 20 years of the Republic of China, the proction cost of drilling and blasting mining increased, coupled with many taxes, the price of tungsten sand rose to more than 25 yuan per 100 catties
in the 22nd year of the Republic of China, Yu hanmou Department of the Guangdong army stationed in Dayu sent personnel to Xihuashan to register and manage the migrant workers and sheds. Thus, more than 20 years of history of completely free mining in Xihua mountain was ended, and the "government supervised private" business mode of official management and private mining appeared< In 1934, the tungsten ore in Xihuashan began to be collected and sold by various sand collecting companies in Dayu county to Jiangxi Tungsten Mining Bureau, which then entrusted Jiangxi Yumin bank to operate the transportation and marketing on its behalf. Because it was on the eve of the Second World War and the fierce arms competition among various countries, the price of tungsten sand rose from 30-40 yuan per 100 catty to 80 yuan, and then stabilized at 60 yuan. On March 13 of the same year, approved by the Ministry of instry and Commerce of the national government and submitted to the Executive Yuan for the record, the state-owned tungsten mining area was demarcated in Xihuashan, covering an area of 1100 hectares and 90 hectares. According to Article 55 of the detailed rules for the implementation of the mining law, the state-owned tungsten mining instry was registered in accordance with the law. In the 25th year of the Republic of China, the Resources Committee of the Central Military Commission of the Kuomintang ordered the military reclamation Department of the first group headquarters of the Guangdong army to organize an investigation team to investigate the exploitation and purchase of tungsten sand in Xihua mountain. In July, after the Guangdong army withdrew from Dayu, the tenth Office of Jiangxi tungsten instry management office was set up in Dayu county. The office is composed of a director, a clerk and a clerk. It is specially responsible for the management of Xihuashan
