You can check it on the website of the fund you bought. Use the ID number you used to open an account as your account number. Each fund company has different regulations for the password. Generally, it is the last 6 digits of your ID card. You can just change it after entering.

In addition, since you have already applied for a bank card from China Construction Bank, why not invest in funds through the direct sales center of the fund company?
