In order to resolve the "safety concern" about schools developing Wushu Sanda, and to boost the smooth development of campus Wushu Sanda, the authors studied "hits and judgment criteria", "technical fouls and personal fouls" and "foul penalties" in school Wushu Sanda competition by applying research methods such as literature data, expert interview and experiment, and concluded that "no thump" as a competition rule has a high degree of safety and good operability. Schools developing Wushu Sanda should base the guiding outline on "no thump", adopt the idea of controlled hitting and touching, let "hits" be determined by offense, defense and control, and weaken their requirement for hitting power, so as to assure the safety of competition participating students.
