Perhaps you should try some spelling variations:
gang wong » gang gong, gang sung
dan yang » daun yang, tan yang, wang yang
yan guan » gan guan, yan yuan, yang guang
wong siu » wong shiu, kong siu, wong sau
dong di » dong sin
ping ku » ping ke, ping yu
ku gang » xu gang, yu gang, zum gang
wang » wan, lang

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 OR wing) yan) OR (dong di)) ((dan yang) OR (yan guan)) ping ku gang wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: (((wang or wing) yan) or (dong di)) ((dan yang) or (yan guan)) ping ku gang wong siu ;*.
