Perhaps you should try some spelling variations:
weng minh » sang minh
chen weng » chen wang, chen zheng, chen rong
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang jui
yang yi » yang di, yang jui
yu chen » yu cheng, yi chen, yulu chen
hong ng » hong kong, hong jong, hong hong
hong g » hong w, hong 7, hong a

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang xi) or (yang yi)) ya yu chen weng minh ((wong sau) or (((hong g) OR (hong ng)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang xi) OR (yang yi)) ya yu chen weng minh ((wong sau) OR (((hong g) OR (hong ng)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang xi) or (yang yi)) ya yu chen weng minh ((wong sau) or (((hong g) OR (hong ng)))) ;*".
