Perhaps you should try some spelling variations:
dang binh » dong bin, dang anh, sang minh
john wong » john song, john bonn
dann bin » dong bin
tran hua » tan hua, tuan hua, tran duc
pei yang » wei yang, pei yun, yi yang
hui yang » hui ying, du yang, h yang
wong sau » wong sam, wong siu, wong shiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dang binh) OR (dann bin)) tran hua ((((pei yang) or (hui yang))) or (ren yan)) john wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dang binh) OR (dann bin)) tran hua ((((pei yang) OR (hui yang))) OR (ren yan)) john wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dang binh) OR (dann bin)) tran hua ((((pei yang) or (hui yang))) or (ren yan)) john wong sau ;*".
