I had an uncle (my father's oldest brother) who was in the Navy and spent most of the 1930s in China, until the Japanese invasion. He was a hard-hat diver. I never knew much about him, but he allegedly married a Chinese woman who, I have been told, died shortly after they got married. An interesting character - he joined the Navy during WWI at age 15 - he lied about his age, and stayed in all through WWII, during which he spent all of his time stateside, doing something in D.C. He later became a Navy civilian employee after his retirement. I saw him once, but briefly, in 1961. Every time I see the Sand Pebbles, I think about him and would have liked to have heard his stories.
