I opened a Xiamen International Bank Card for no apparent reason.

Telecom fraud is common nowadays, and criminals often use false information to open accounts, buy and rent other people's bank accounts, etc. to launder money and transfer stolen money. The China Banking Association stated that "renting or lending bank cards is illegal and can easily lead to the risk of subsequent theft. At the same time, if the bank cards rented or loaned are used for money laundering or other illegal transactions, even if the cardholder has no knowledge , may also bear joint liability."
