You must go to the bank where you open an account. If your information is not leaked, remember your card number. You can deposit it directly into the Agricultural Bank of China, or you can repay it with a passbook, because the repayment effect is the same when the card is converted into one. To open online banking, you can open it on the website of Agricultural Bank of China at any time. You'd better reissue a card, which is more convenient.
