Personally, I think it's quite formal, and 10 has been established for several years, and all the necessary documents are available.

Boya education fee: Boya education newspaper undergraduate fee 10800, which is relatively expensive. I also asked some other institutions, which are basically around 8K.

Boya's education classes are all recorded and broadcast live, and the level of classes is far from good. Some are ok, some like watching PPT, and some are only in their twenties. I guess I haven't graduated yet. Anyway, there are many part-time teachers.
