As a Chinese grew up in Taiwan, i can tell you these are not made up. Here's Wikipedia quote from Shocking Asia:
Shocking Asia is a 1974 documentary film written and directed by Rolf Olsen with Ingeborg Stein Steinbach. The film was banned in Finland due to its graphic content. A sequel titled Shocking Asia II: The Last Taboos was released in 1985.
