How do national Sanda athletes divide into first and second grades? Pray for the great gods.

Simply put, the first-class athletes play the national competition and the second-class athletes play the provincial competition. The second-class athletes are equivalent to the coaches of Wushu schools, and the first-class athletes are equivalent to the intensive classes of Wushu schools (each school has a different name, that is, the well-formed classes of the whole school). I am a second-class athlete and a second-class soldier, hehe.
