Perhaps you should try some spelling variations:
kong hang » kong heng, kong hong, kong land
yan tang » yan wang, yang yang, tang tang
yang jui » yang judy, yang di
wan yan » wang yan, nan yan, wai yan
yang xi » yang di
yang yi » yang di
so can » so cap
o can » _ can, 3 can, 4 can

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: wan yan tang ((o can) OR (so can)) ((yang xi) OR (((yang jui) OR (yang yi)))) kong hang ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan tang ((o can) OR (so can)) ((yang xi) or (((yang jui) or (yang yi)))) kong hang ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan tang ((o can) OR (so can)) ((yang xi) or (((yang jui) or (yang yi)))) kong hang ;*.
