Perhaps you should try some spelling variations:
oanh tran » binh tran
yang john » young john, king john, yang jin
john wong » john song, john bonn
anh tran » binh tran
anh tuan » dinh tuan
hua chen » yu chen, a chen, hua ren
jui chen » yi chen
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: wang ((((oanh tran) OR (anh tran))) or (anh tuan)) ((hua chen) or (jui chen)) yang john wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((oanh tran) OR (anh tran))) OR (anh tuan)) ((hua chen) OR (jui chen)) yang john wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((oanh tran) OR (anh tran))) or (anh tuan)) ((hua chen) or (jui chen)) yang john wong sau ;".
• Adding a wildcard symbol may retrieve word variants: wang ((((oanh tran) OR (anh tran))) or (anh tuan)) ((hua chen) or (jui chen)) yang john wong sau ;*.
