yuhan ming » yuan ming, chan ming
yuan wang » yan wang, yuan kang, qian wang
ming kong » king kong, sing kong, hong kong
wing yan » wang yan, wing ian, wing tan
kong siu » kong eiu, wong siu, kong sar
sin » sign, sind, skin

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 yan) OR (((dong di) OR (dong sin)))) ya ((yuan wang) OR (yuan chang)) yuhan ming kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) or (((dong di) or (dong sin)))) ya ((yuan wang) OR (yuan chang)) yuhan ming kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (((dong di) or (dong sin)))) ya ((yuan wang) OR (yuan chang)) yuhan ming kong siu ;*.
