I have seen this advertisement, too. The reward is real, but you should think about what he promised you. Yucai High School is a part of Yucai Middle School. The school has primary school and junior high school, so it won't put all its energy into senior high school, let alone review lessons. There are not many students in Yucai School, and the students are not very good, so they will publicize it everywhere. It's a private school for making money. I don't deny that there are good students and teachers among them, but the overall level is very general in Hebi Normal School. A few years ago, the school environment was good, but now the school is old and the environment is average.
You should think it over!
