Mao and traditional kung fu in mainland China. The Communist revolution China appears to have had devastating results in mainland China. Bad enough when Mao came to power- much worse with the Cultural revolution. Chen taiji survived despite terrorization by Red guards. Chen Xiao wang has brought about a great revival despite the damage to his father. Some Xing Yi and Pakua folks went to Taiwan, SEsia and elsewhere. Later showy wu shu emerged."Martial" became an unwelcome legacy. In wing chun-Ip Man left for Macau and then Hong Kong.Even though a couple of his early disciples were left behind IM took much with him. Neither WSL or HKM thought that any good wing chun was left on the mainland. Then with videos you see the see-do versions. But then even in the UK and US video watchers seem to abound. I am just sharing a view point.
