1. The premise of applying for the temporary line is that the credit is good and there is no overdue record.

2. The temporary quota can be up to 50% of the fixed quota. In case of big holidays, it can be increased by 20% on the basis of (fixed quota +50% temporary quota), totaling up to 80%.

3. If the temporary quota has never been used before, and the proportion of the quota usually used is not high, the initial application may not give you a one-time increase, or even a temporary adjustment.

4. If part of the temporary quota applied for is insufficient, you can continue to apply until it is close to 50%.

5. Temporary line can also be withdrawn and paid in installments. (But the 20% temporary quota for holiday adjustment is generally not available, but I took it. )

6. The temporary quota can be limited for 30 days. If you haven't used it up, you can continue to apply. For example, if you apply for a temporary quota of 50%, but only 20% will expire, you can continue to apply for a refund of 50% until the remaining 30% is used up.

7. The temporary limit may not need to be fully repaid in the next bill.
