Perhaps you should try some spelling variations:
chan going » china going, chan fong, chan ming
heung chan » cheung chan
going long » going wrong, going one, qing long
long thanh » luong thanh, long han, long trinh
wang ning » wang jing, wang liang, wang yang
han heung » hin cheung, han kyung
yang xi » yang yi, yang jui

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: (wing OR lang) ((wang ning) OR (((yang xi) OR (yang di)))) han heung chan going long thanh ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((wang ning) or (((yang xi) or (yang di)))) han heung chan going long thanh ;*.
