At that time, I visited the fitness instructor training school in Yantai and had no choice. The Star Channel Fitness College, which was finally selected, tailored one-on-one class design for students of different foundations and categories. Through one-on-one teaching, I pointed out the students' problems more pertinently, and implemented teaching in strict accordance with the comprehensive and systematic "teaching method". After graduation, four certificates were issued, one international coach certificate and one national certificate, which were much more formal than Yantai.
