dong bin » dong sin, dong di, dann bin
yan kong » tan kong, yan cong, nan kong
hua wai » hua wei, chun wai, phua kai

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 bin)) ya hua wai yan kong heng g ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (dong bin)) ya hua wai yan kong heng g ;*.
