What are the national Tai Ji Chuan competitions?

As long as the Tai Ji Chuan competition approved by the National Sports Federation belongs to the national Tai Ji Chuan competition, the Tai Ji Chuan competition held anywhere does not belong to the national Tai Ji Chuan competition, and some local Tai Ji Chuan competitions are generally crowned with bigger names, such as the international Tai Ji Chuan Friendship Association or exchange meeting, mostly for making money. Some places are the birthplace of Tai Ji Chuan. Under this banner, "X XXX International Tai Ji Chuan Exchange Conference" will be held every year. Don't say that the state admits it or not, even the local sports bureau and the education bureau don't recognize their academic qualifications. They only aim at making money, so they should be careful not to be cheated.
