I recently met a man who grew up in Hong Kong in the 1950s and said that he often went to chimpanzee/human wrestling matches as a form of entertainment during his childhood and teenage years. I tried to google, but couldn't find much beyond youtube videos of individuals wrestling chimpanzees. Was chimpanzee/human wrestling a common form of entertainment in Hong Kong? What about other areas? Any added details regarding prices, usual outcomes, etc would also be appreciated.
