There are two ways: 1. You can go to the counter of China Agricultural Bank's business outlets with relevant certificates and ask the staff to help you inquire, or you can inquire on the inquiry machine in the bank lobby (if you can't use it, you can ask the lobby manager to help you operate it). 2. You can log in to official website/of China Agricultural Bank, log in to your bank account first, and then you can inquire after finding this option in the business inquiry office.
