kong saur » kong sar, kong siu, kong your
yan guan » gan guan, yan yuan, yang guang
chen han » cheng han, chen hao, chen tan
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
wong siu » wong shiu, kong siu, wong sau

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: yan guan chen han chang ((yang jin) OR (yang jie)) ((wong siu) OR (kong saur)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan guan chen han chang ((yang jin) OR (yang jie)) ((wong siu) or (kong saur)) ;~".
• Adding a wildcard symbol may retrieve word variants: yan guan chen han chang ((yang jin) OR (yang jie)) ((wong siu) or (kong saur)) ;*.
