There are many secret English training institutions in Changsha. There is one in Tianma apartment of Hunan University where I study. It's really good. They are short of teachers now, and they will definitely have jobs. Training 15 days, the cost rose to 1380. However, early registration will be preferred. I paid a deposit of 100 in advance, and then I only paid 1200. I finished my class the day after tomorrow. Be sure to teach your brother when you go home. This method is really good. It is absolutely different from all other training institutions that focus on traditional English education.
