The historical balance of not using Confucius' old book network.

Software defects. Confucius second-hand book network is a professional second-hand book trading platform in China. It has gathered tens of thousands of online bookstores and bookstores across the country and displayed as many as 90 million books. Some users have a bug in the software platform when their historical balance is not used. By the end of 2022, the bug has been fixed and users only need to reopen the platform.
