Perhaps you should try some spelling variations:
thanh dam » than daem, thanh van
daun yang » du yang, tan yang, un yang
wang van » wang yan, wang ban, wang dan
thanh vu » thanh van, thanh _
ren yang » ren yan, chen yang, pei yang
dan yang » tan yang, wang yang, yang yang
tin wong » tin hong, t.j wong, kie wong
wong yi » weng yi, wong y, wong lai

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 van ((thanh vu) OR (thanh dam)) ((((ren yang) OR (dan yang))) OR (daun yang)) tin wong yi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang van ((thanh vu) or (thanh dam)) ((((ren yang) OR (dan yang))) or (daun yang)) tin wong yi ;~".
• Adding a wildcard symbol may retrieve word variants: wang van ((thanh vu) or (thanh dam)) ((((ren yang) OR (dan yang))) or (daun yang)) tin wong yi ;*.
