I've been in this situation, and it's been solved. The reason is that you bought precious metals in your account with a second-class account (e-bank account). In principle, second-class accounts cannot buy precious metals, but it may be a system bug. Finally, you can buy it, but the position is not displayed. Solution: You need to go to the nearby Bank of China business hall and get a physical card first. If you have a physical card, you don't need to do it (a first-class account). Then, ask the wealth management manager (don't ask ordinary employees, they don't understand) to follow the transfer process (if the wealth management manager doesn't understand, ask him to call his superiors), that is, transfer the precious metals held in the secondary account to the primary account (this process does not involve the trading of precious metals, but only the share of precious metals).
