After opening the page of Tianjin Basic Education Resources Public Service Platform, you enter the course without any data. If users encounter no data display when using it, it is because of a BUG in this version.

This BUG is fixed in the background, and it can be used normally. Now bugs have become the general name of software vulnerabilities, defects and errors. Hackers often invade from software or program vulnerabilities, so bugs have become a problem that program developers and programmers often need to deal with.
