About postal savings. Help explain the following deduction? How can I not buckle?

Hello, "short deduction fee" is a short message notification service (account change reminder service) of China Postal Savings Bank, and it is charged. The charging standards vary from province to province. Some provinces collect money on a monthly basis, 3-5 yuan per month, and some provinces collect money on an annual basis, 30-60 yuan per year. I suggest you check with the local Postal Savings Bank for details. After you cancel your card and ID card at the counter, there is no charge. "Small amount" refers to the small account management fee charged by 3 yuan for the RMB current deposit account with the daily average account balance of the quarter less than 100 yuan; Issue social welfare fund accounts such as subsistence allowances, social security and pensions; Handle current accounts authorized to pay utilities such as water, electricity, gas and telephone; A current account for repayment of personal loans and automatic repayment of credit cards; A current account for purchasing funds, RMB wealth management products, national debt and insurance products; Open a current account for third-party depository business; There is a green cartoon current main account and a local and foreign currency sub-account during the charging period; All current accounts and other accounts under VIP customers' names are exempt from small account management fees. I hope I can help you.
