How about Changsha Hongxing Lin School?

First, the regularity of the school. At present, the relevant qualifications and school licenses of private schools can be found in Hongxing Forest in Changsha, and all Hongxing Forests are legal and formal training institutions.

Second, the strength of the school. According to official website of Hong Xinglin, more than one million students have been trained, and the mainstream courses are 10. It belongs to an established training institution. After such a long period of accumulation, a group of excellent teachers have gathered and the curriculum system is very complete.

Third, word of mouth. On the contrary, I think this is the most important point, because teaching is perfunctory and attitude is poor. Presumably, even the best teacher will not learn much, but will be more wronged. You can check the overall reputation of this company on forums such as Post Bar and Zhihu. What you have seen so far is feedback, but you need to know more.
