From top left, clockwise: Fu Zhongwen, Dong Ying Jie, Zheng Manqing (Chen Man Ching), and Yang Zhenduo (son of Yang Chengfu and grandfather of Yang Jun).
Fu Zhongwen, prominent disciple of YCF, sets the pace here; all the others are slowed down or sped up to sync with his steps. Of course, CMC only had the short 37 form, so not all of his movements are here. Others shortened some parts of the form so occasionally these videos fade out momentarily.
