China Post's bank card is blocked, and proof of income is required. If there is no specific proof of income, the treatment method is as follows:

1. Personal assets certificate: If you have personal assets or property, such as real estate license and vehicle license plate, you can provide these certificates as proof of your financial ability.

2. Proof of deposit: If you don't have proof of income, but you have a certain amount of deposit, you can apply for a certificate of deposit from the bank to prove that you have some funds in the bank.

3. Income ranking table: If you are a freelancer or entrepreneur, you can provide your latest income ranking table to prove your income.
