I think this is one of the best historical videos of Tai Ch you’ll find. I’ve seen this film before, but the quality wasn’t great. This version of the Tai Chi documentary however seems to have been edited to make it smoother and sharper:
In the video you’ll find the most famous masters teaching Tai Chi in Beijing in the 1950s. It’s a good cross section of the different styles being taught. The masters are (and I think I’ve got the order correct): Li Yaochen, Li Bingqi, Chen Zhaokui (the youngest son of the famous Chen style patriarch, Chen Fake), Yang Yunting, who learned from Quan Yu, who was a direct student of Yang Lu Chan. Sun Jianyun (daughter of the famous Sun Lu Tang). Wang Yongquan, who performs the Yang long form and was a student of Yang Jianhou and Yang Shouhou. And finally Li Jing Wu, who was a student of Wu style and Chen style, but here is performing the Beijing 24 step form.
