Sau-king YEUNG (aka 楊秀瓊, Yvonne TAN, YANG Xiuqiong) [1919-1982]
Yeung Sau-king (nicknamed "Mermaid") was a famous Hong Kong swimmer and Olympian who was active in the 1930s. She represented Hong Kong in two Chinese National Games (1933, 1935), and represented China in the 1934 Far Eastern Championship Games and 1936 Olympic Games. She broke multiple swimming records of Hong Kong, China and the Far East. She was a secret agent for China in Japanese-occupied Hong Kong, and became a leader in life saving in the 1960s. There is a lot of false information about her on the internet based on untrue reports in 1940s tabloids. Linda Pun, a journalist based in Hong Kong, conducted detailed research on Yeung's life and wrote her biography (in Chinese) in 2019. She also wrote a brief biography in English.
