After Ping An Bank's credit card is downgraded, users need to take the initiative to apply to Ping An Bank if they want to return to the original limit within 3-5 days. If the reason for the decrease is suspected of cashing out or stealing, users can submit their own consumption receipts as vouchers, indicating that consumption is not illegal. Ping An Bank will restore the user's original credit card limit within 3-5 days after it has passed the examination and confirmed that the user has not violated the rules. And the user does not have enough proof materials for Ping An Bank to review, so it is basically impossible to restore the credit card to the original limit within 3-5 days.

1. refers to the amount that the lender can borrow from the borrower without providing property guarantee. It usually means that a natural person borrows money from a bank, and the bank is willing to provide the highest amount of loans according to the credit status of the individual. This amount will be determined unilaterally by the bank because of income, income, debt ratio, work content, company, company position, property and so on. This kind of lending relationship is usually that banks lend money to natural persons. On the other hand, it is usually necessary for commercial organizations and transnational exchanges to lend money to organizations. Because the credit line is an unsecured loan line, it is usually not too high, and this line will be determined according to the conditions provided by the borrower. This means that the borrower must have a higher credit line, and all the conditions of the borrower must be quite good, so that the lender will be willing to provide a higher loan line.

Second, the relationship limit: if ICBC has more than two credit card users, it actually uses a higher credit card limit, and the credit card with a lower credit limit actually uses a higher credit card limit. If you swipe a credit card with a lower credit limit, not only the credit card with a lower credit limit will be deducted, but also the credit card with a higher credit limit will be deducted accordingly. Generally, ICBC informs the card amount, but due to the influence of the relationship amount, the actual cardholder can't use the card amount, so the relationship amount. For example, ICBC has two cardholders' cards, one with a quota of 3,000 yuan and the other with a quota of 10000 yuan. After the cardholder spends 3,000 yuan on a card with a limit of 3,000 yuan, the card only has a limit of 0 yuan, and another card with a limit of 10000 yuan has also been reduced by 3,000 yuan, leaving a limit of 7,000 yuan. This is the so-called relationship limit.

3. Geomechanical terminology: restriction is a kind of composite structural system, which refers to the composite phenomenon that structural members in two different periods have significantly different trends, and the later structure ends in the earlier structure. This phenomenon is named because it is limited by the early structural interface. The latter structure is called restricted structure, and the former structure is called restricted structure. Restricted structures can be secondary structures or primary structures, and most of them are secondary structures. This compound phenomenon is also found in vein deposits. According to the constraint relationship, the relative period of composite structural members can be judged.
