1. Bank of Communications: Bank of Communications is the first to bear the brunt. Bank of Communications is well-known in the circle for its strict risk control, which is unmatched by others. Not only is it difficult to raise the amount, but sometimes it inexplicably prompts abnormal consumption. As long as it is discovered once, the amount will be reduced immediately, and the tens of thousands will drop to thousands immediately, not to mention the second drop.

2. CITIC Bank: CITIC's risk control is also very magical, and it likes to take a surprise without warning. For example, it is urgent to withdraw money once, and then it will be reduced after withdrawal. If you place a large card, if you don't swipe it often, it will be reduced. There is no mercy, and sometimes it will not even be phased. In short, the situation will continue.

3. Shanghai Pudong Development Bank: Shanghai Pudong Development Bank often raises the amount first, and then it has to pay 1, yuan in installments within a certain amount, otherwise it will restore the original amount, which is a bit shameless and not easy to provoke.

4. Ping An Bank: The risk control of Ping An Bank is also strict, and there are times when it is easy to reduce the amount. Sometimes a phone call is made to promote installment and insurance. If it is not phased, the amount may be reduced.

5. Guangfa Bank: Guangfa is more suitable for cardholders who can raise the amount by swiping their cards. It is easy to brush and raise the amount, and it will not be used for several years without a limit.

6. China Merchants Bank: It is very quick and simple for China Merchants Bank to raise the amount in the early stage. However, China Merchants Bank's small black room has always been very frequent, and it is always closed to the black room if it swipes its rights and gives points.
