What is this? I don't have a China Merchants Bank card at all. Why did you send this to me?

Never mind, 1. I did run a business myself, but now you don't remember, which means you have basically no business dealings with the bank. No business, it doesn't affect you. If you want to do business, it's not too late to get your ID card.

2. It may be a liar or an information acquisition. If you have no business, you say you have done business. If you go to the bank with your ID card to inquire about the situation, the bank will mark you to a certain customer group and get your identity information (now it's mass mailing, and I don't know who received it. If you go to the bank, the bank will know your ID card and mobile phone), which is convenient for the bank to promote in the future.
