I personally recommend Tu Hua, because their courses are job security, equal enrollment, small class closed teaching, equal enrollment according to the position of 1: 1, small class closed teaching, and actual combat drills for groups of 6-8 people, which fully guarantees the time for students to simulate actual combat drills and teachers' personalized counseling. The effect is good and the teacher is more authoritative. Tu Hua is in Zhaotong, in the lobby on the first floor of Huacheng Hotel diagonally opposite Zhaotong Agricultural School. The telephone number is 0870-2239705. You can call for advice! Good luck!
