First of all, one of their principals commented that "they are the first listed primary and secondary education enterprise in China, which is actually very good, but it seems that they can't be found in first-tier cities because they mainly provide personalized teaching services to children in second-and third-tier cities. I am from Jimo, Shandong Province, and their support is still in place. The main thing is that we will give them feedback if we have any problems, and they will always solve them in the first place.

Secondly, I searched a lot of information about them from Baidu, and I feel it is quite reliable, because it is outstanding in terms of teachers and the number of schools.

I hope my answer can help you. If you don't understand anything, you can keep asking me.
