A friend earned more than 100 through investment, which is equivalent to about 800,000 yuan. He decided to withdraw half of the funds. However, things didn't go as planned. After completing the withdrawal operation in the morning, I received a call from the bank in the afternoon, asking about the source of funds, workplace, and requesting relevant supporting documents. Especially when it comes to virtual currency (U currency) transactions, once the amount is large, the risk of freezing by the bank increases significantly, and you may even face a "tea drinking" investigation.

According to the "Management Measures for Customer Due Diligence of Financial Institutions and Preservation of Customer Identity Information and Transaction Records" issued by the People's Bank of China and other departments, financial institutions must identify and verify when handling a single RMB deposit and withdrawal business of more than 50,000 yuan for customers. Customer identity, and register the source and destination of funds.
