Perhaps you should try some spelling variations:
wang oanh » wang yan, wang yang, dang anh
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
wong sam » wong sau, wong lai, kong sar
tran vu » tran van, tran duc
tuan vu » thanh vu, tuan hua
yang yi » yang di, yang xi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang oanh ((tran vu) OR (tuan vu)) chen ((((yang jin) or (yang yi))) or (yang jun)) wong sam ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang oanh ((tran vu) OR (tuan vu)) chen ((((yang jin) OR (yang yi))) OR (yang jun)) wong sam ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang oanh ((tran vu) OR (tuan vu)) chen ((((yang jin) or (yang yi))) or (yang jun)) wong sam ;*".
