I think my math teacher, Miss Zhou, has the greatest influence on me.
Every teacher here is very responsible. I went to my grandfather's house the other day. It seems that the doors there have also been repaired, which is definitely much better than the environment of our session. But it doesn't mean that the environment is good and the teaching is poor. The answer is no. The teaching quality there is very high. If you are lucky enough to meet Miss Zhou, you will be very lucky. In a word, Yancheng Tian Jiabing Primary School is really a good school.
But even the best schools need children who are willing to learn. I don't know what you or your children are like.
The above is just my personal opinion. Whether you go or not depends on your own choice.
