A: When dealing with overdue debts, according to the relevant laws and practices in China, under normal circumstances, the repayment order of online loans and credit cards is online loans first and then credit cards. The following is a detailed explanation:

1. The law stipulates that according to the Contract Law and the Consumer Protection Law of China, the loan contract shall be performed as agreed. If there is no agreement, the repayment order shall be determined according to factors such as repayment ability and repayment willingness.

2. Conventional practice: Most online loan companies will specify the repayment order in the contract, and usually put online loans first. In addition, credit cards usually adopt the minimum repayment system, which means that their repayment priority is low.

3. Overdue consequences: Overdue repayment may lead to the accumulation of interest and late fees, and will also affect personal credit records and be punished accordingly.
