Legal analysis: Banks operate legally and all projects are approved by CBRC. Whether credit card lending is illegal or not depends on the way the lender overdraws the credit card to get cash. It is not illegal for a lender to obtain a cash loan by withdrawing cash from a credit card. If the lender circumvents the cash withdrawal method provided by the bank, it is illegal for the lender to withdraw the credit card in cash through false transactions, such as personal POS machines or third-party cash withdrawal platforms.

Legal basis: Article 196 of the Criminal Law of People's Republic of China (PRC) commits credit card fraud under any of the following circumstances.
