rein chang » chin chang, jin chang
longer do » longer _, longer a, long do
wang nan » wang yan, wang ban, wang dan
hua rein » hua ren, hua wei, a rein
chang ha » chang mae
wong sau » wong sam, wong siu, wong shiu
nan yan » nan ya, wang yan, qian yan
yan hua » tan hua, ya hua, wang hua

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 nan yan hua rein chang ha ((wong sau) OR (longer do)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang nan yan hua rein chang ha ((wong sau) or (longer do)) ;*.
