High cost performance and noisy.

1. The environment of Zhengzhou Aired is very good, the dormitories are very clean, the teachers have their own characteristics and have a strong sense of responsibility. It is a very good school with a very high cost performance.

2. The bell time of Zhengzhou Aired School is set unreasonably. Even when students are not in class on weekends and holidays, the bell still rings and the sound is very loud.
