Yeah. He’s from Vietnam apparently, hence the name. But he’s Chinese.
Could be from southwest China and uses a weird Vietnamese type spelling.
Tran is Chen in Mandarin. His name is 陳友艮。
When I was in Vietnam, many decades ago, I met quite a few ethnic Chinese, in (by Physical area) a very large China town, the Cho Lon district of Saigon. There was a nice Army PX we used to go to, even though we were USAF, at Bien Hoa.
