Perhaps you should try some spelling variations:
long thanh » luong thanh, long han, long trinh
china won » china women, china wang, china who
dang haji » dang hai, dato haji
chia tan » chia lan, chen tan, chia wen
nan yan » wang yan, qian yan, dan yang
yang li » yang lin, yang di, yang xi
nan ya » nana yaa

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: wang ((nan ya) OR (nan yan)) ((chia tan) OR (china won)) yang li ((long thanh) OR (dang haji)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((nan ya) OR (nan yan)) ((chia tan) or (china won)) yang li ((long thanh) or (dang haji)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((nan ya) OR (nan yan)) ((chia tan) or (china won)) yang li ((long thanh) or (dang haji)) ;*.
