I had the same confusion today, so I came to Baidu and found one by accident. I went to China Construction Bank today and deposited 10000 on a regular basis. After the deposit, there is no receipt and no signature. I didn't think it was appropriate at that time, but I didn't think about it carefully. When I came back to ask my colleagues, they were all surprised. Let me ask them again, so I went to the bank to confirm it again. As a result, I was told that there is no need to sign for deposits below 50,000 yuan, and there is no need to sign for withdrawals. I don't study law, but I think there may be loopholes here, so in order to avoid unnecessary troubles in the future, I took out all my deposits and deposited them in other banks, not to mention which bank, but this bank has to sign how much it deposits and has a deposit receipt.
