4. Bonus system is not the key to success, so we should choose it carefully

5. You can press the power on button for more than 10 seconds to shut down and restart. If the operation is invalid or the problem remains, it is recommended to send the mobile phone to the nearest service center for detection and processing.

6. There are many reasons for cell phone card crash, and the following two reasons are listed:
first, if the hardware is damaged, it may also cause frequent crash. Mobile phone is a precision electronic proct, and its circuit must work normally in a relatively stable environment. If the mobile phone often works in a humid environment or is strongly shocked by the outside world, It may crash.
for example, sometimes when we accidentally drop our mobile phone on the ground, it may crash. So we must treat our mobile phone kindly and handle it gently; Don't let the mobile phone get into the water, try not to use the mobile phone in the humid environment.
usually, if we operate the mobile phone improperly, it will also cause the mobile phone to crash. Especially when we are sending short messages, if the speed of key operation is too fast or we are bombarded by short messages continuously in a short time, the CPU load of the mobile phone is too large, and the heat generated by the CPU can't be emitted in a short time, Therefore, when we use the mobile phone, we must pay attention to the operation; Besides, try not to disclose your mobile phone number to avoid short message bombardment.
in addition, there are other factors leading to the crash e to hardware problems, such as the aging of hardware, the bad use environment of mobile phone, etc.
Second, software problems
are mainly caused by fatal bugs in the software design of mobile phone. For example, When the mobile phone runs a program, if there is a logic error between the subroutine and the main program, every time the mobile phone runs to the program, there will be an instruction error, which is a bit like the illegal operation in the computer. At this time, there may be a crash. The crash caused by the bug of the software generally has such characteristics: whenever it runs to a certain command, it will cause a crash, That is, every time you perform the same operation, there will be a crash.
if your mobile phone always crashes like this, it can be preliminarily determined that it is e to the software problem. To solve such a crash, you can generally upgrade the software. Now all major mobile phone manufacturers have customer service centers, which provide free software upgrade services, Such an upgrade can only upgrade the software version, and the function of the mobile phone will not change after upgrading. However, some software bugs are solved ring the upgrade, which reces the probability of crash. Now many DIYer mobile phones like to upgrade the software of the mobile phone, which causes instability to the mobile phone, so it's best to go to the customer service center to upgrade the software of the mobile phone, If you upgrade yourself, please make a backup in advance, so as to avoid the software can not be recovered after the upgrade failure.
in fact, the mobile phone crash is as normal as the computer crash. As long as we treat it correctly, there will not be so many people complaining about their mobile phone crash again. But if your mobile phone often crashes, you should pay attention to it, It's better to send your love machine to the customer service center for maintenance.

7. Currency swap
the characteristics of currency swap

also known as "currency swap", refers to the exchange of a certain amount of currency with another certain amount of currency within a certain period of time

function

currency swap is a commonly used debt hedging tool, which is mainly used to control the medium and long-term exchange rate risk, and to convert one kind of foreign exchange denominated debt or asset into another kind of foreign exchange denominated debt or asset, so as to avoid exchange rate risk and rece cost. The early "parallel loans" and "back-to-back loans" had similar functions. However, whether it is "Parallel Loan" or "back-to-back loan", it still belongs to loan behavior, which will proce new assets and liabilities on the balance sheet. As an off balance sheet business, currency swap can achieve the same purpose without affecting the balance sheet

for example, the company has a Japanese yen loan with a term of 7 years and a fixed interest rate of 3.25%. The interest payment date is June 20 and December 20 every year. It was withdrawn on December 20, 1996 and returned on December 20, 2003

after the company withdraws money, it will buy Japanese yen into US dollars for purchasing proction equipment. The income from exports is in US dollars, but not in Japanese yen

from the above situation, we can see that the company's yen loan has exchange rate risk. Specifically, the company borrows Japanese yen and uses US dollars. On December 20, 2003, the company needed to convert us dollar income into Japanese yen for repayment. Then, if the yen rises and the US dollar falls (relative to the exchange rate at the beginning of the period), the company will have to use more US dollars to buy yen for repayment. In this way, because the company's yen loans are not unified in terms of borrowing, using and repaying, there is exchange rate risk

in order to control the exchange rate risk, the company decided to conct a currency swap transaction with BOC. Both parties stipulate that the transaction will take effect on December 20, 1996 and expire on December 20, 2003, with the exchange rate of USD1 = jpy113. This currency swap is expressed as:

1. On the withdrawal date (December 20, 1996), the company and BOC swap principal:

the company withdraws the loan principal from the lending bank and pays it to the Bank of China at the same time, and the Bank of China pays the company the corresponding US dollars at the agreed exchange rate< 2. On the interest payment date (June 20 and December 20 each year), the company and Bank of China swap interest:

Bank of China pays interest in Japanese yen to the company at the interest rate level of Japanese yen, the company pays interest in Japanese yen to the lending bank, and at the same time pays interest in US dollar to Bank of China at the agreed interest rate level of US dollar< 3. On the maturity date (December 20, 2003), the company and BOC swap the principal again:

the Bank of China pays the principal in Japanese yen to the company, the company returns the principal in Japanese yen to the lending bank, and pays the corresponding US dollar to the Bank of China at the agreed exchange rate

it can be seen from the above that at the beginning and end of the period, the company and BOC swap principal at the same exchange rate (USD1 = jpy113) which is prescribed in advance, and ring the loan period, the company only pays interest in US dollars, while the interest in Japanese yen is used to restore the interest in Japanese yen loan, so that the company completely avoids the risk of exchange rate changes in the future

there are several points to be explained about currency swap:

the interest rate form of currency swap can be fixed for floating, floating for floating, or fixed for fixed. Generally speaking, the maturity of major foreign currencies can be 10 years

the exchange rate stipulated in the currency swap can be spot rate or forward rate, or any other level as agreed by both parties, but the interest rate level corresponding to different exchange rate levels will be different

in currency swap, the principal swap at the beginning of the period can be omitted, that is, step a) in the above example may not exist, but the corresponding interest rate level of US dollar may be different. In this way, for those loans that have been withdrawn, currency swap business can still be used to manage exchange rate risk<

handling proceres

the interest rate swap application signed by the company's legal representative or authorized signer, stamped with the official seal and signed by the original lending bank shall be used to sign the currency swap agreement, and the original lender shall provide the continuity guarantee under the swap transaction and make an inquiry at the bank Joint venture, cooperative and joint-stock companies should submit the resolution of the board of directors)

swap right

swap right is an interest rate swap or currency swap transaction with an option structure. Specifically, the two parties of an option transaction reach an agreement on the relevant contents of an interest rate swap or currency swap transaction, but the option buyer has the right to decide whether the above swap transaction will take effect on a certain date in the future (European option) or within a certain period of time in the future (American option). As the price of this right, the option buyer needs to pay a certain amount of fees to the option seller

with this proct, the debtor can obtain a more flexible protection on the premise of paying a certain fee, that is, when the market develops in a disadvantageous direction, the swap transaction can be made effective according to the level agreed in advance, so as to lock in the risk; When the market conditions develop in a favorable direction, we can choose not to exercise the option, so as to lock in the risk at a more favorable time.

9. How much foreign currency should a certain unit of currency of a country be converted into and how is the ratio determined? In different monetary systems, the basis of exchange rate determination is different. Under the principal position system, the exchange rate is determined by comparing the gold content of each currency; Under the system of paper currency circulation, the exchange rate is determined by the actual purchasing power of currencies of various countries in the same period

under the principal position system, each country has set the gold content of its own currency. By comparing the gold content of one country's currency with that of another country's currency, we can get the mint parity of the two countries. For example, in 1929, Britain stipulated 113 grains of pure gold in one pound and the United States stipulated 23.22 grains of pure gold in one dollar. According to their gold content, the mint parity of Britain and the United States is 113 ÷ 23.22＝4.8665 In other words, the gold content of one pound is 4.8665 times that of one dollar, that is, the exchange rate of the two countries is one pound = 4.8665 dollars. In the foreign exchange market, e to the influence of supply and demand, the real exchange rate will sometimes be higher than the seigniorage parity, but the fluctuation will not be too large

after the collapse of the gold standard, all countries have generally realized a non convertible paper currency circulation system. Each country's currency no longer publishes the gold content, or although it publishes the gold content, it has already existed in name. The following is to determine the exchange proportion according to the comparison of the actual purchasing power of its currency in the same period. At present, it is generally believed that the exchange rate of the currencies of the two countries can be determined by comparing the price levels of the import and export commodities of the two countries. Due to the frequent price changes in various countries, the exchange rate is often unstable at this time

the price of gold also changes at any time
