Why do Hong Kong keep the traditional martial arts of fighting and fighting, while many martial arts schools in Chinese mainland only teach fancy clothes?

Hong Kong retains the traditional martial arts of fighting and fighting, and the mainland has a decade of Cultural Revolution.

Hong Kong is governed by Britain, but its original traditional culture has been basically preserved. Due to historical reasons, the mainland carried out the Cultural Revolution for ten years, which denied the original traditions, and some of them were directly destroyed, resulting in a cultural gap. Another important reason is that 1988 Wushu is divided into routine and Sanda. The final trend of routine is the artistic expression of offensive and defensive movements. Sanda represents actual combat.
