Perhaps you should try some spelling variations:
yang jie » yang jin, yang di, yang jui
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wai yan
yan ban » can bank, tan bann, wang ban
yang xi » yang di, yang yi, yang jui
a chen » ta chen, _ chen, n chen
ban a » can a, ban _, bab a

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 ban a chen ((((yang xi) OR (yang jie))) OR (yang judy)) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ban a chen ((((yang xi) or (yang jie))) or (yang judy)) wong sau ;*.
