Perhaps you should try some spelling variations:
phan china » han china, than china, wuhan china
duong van » cong van, duong anh
van phan » dan phan, van thanh, van ham
yang jui » yang judy, yang xi, yang yi
yang jun » pang jun, yang jin, yang judy
dong hua » wang hua, tong hui, dong hoi
gang hu » gang zhou, wang hua, wang hui
fall » all, hall, full

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: duong van phan china fall ((((yang jui) OR (yang di))) OR (yang jun)) ((gang hu) OR (dong hua)) ;~.
• Adding a wildcard symbol may retrieve word variants: duong van phan china fall ((((yang jui) or (yang di))) or (yang jun)) ((gang hu) or (dong hua)) ;*.
