How to evaluate the life of Wancang Bu, a famous film director in China?

I admire Wancang Bu very much. He was a famous early film director in China. He became a film director in the mid-1920s. During his 40-year artistic career, he directed and filmed 86 films, some of which not only shocked the China film industry at that time, but also were praised as "the treasures of China films" by international friends when the "China Film Retrospect Exhibition" was held abroad a few years ago.
