Zhao Jianhua, the king of badminton, and Xiao Jie, a former member of the women's team of China's national badminton team, head coach of the International Badminton Federation World Badminton Training Center and badminton professor of the Capital Institute of Physical Education, sat on the court. Through professional demonstrations, detailed explanations and multi-angle demonstrations, the film specifically diagnoses the problems and doubts of badminton lovers in actual combat, tailors exercise prescriptions and improves actual combat skills.
