wang yang » wang yan, wang liang, wang yanling
kong saur » kong sar, kong siu, kong your
hua rein » hua ren, hua wei, a rein
rein yan » ren yan
wong sau » wong sam, wong siu, wong shiu
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, yang jin, pang jiu

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 wang) OR (wang yang)) yan hua rein yan jiu ((kong saur) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yang)) yan hua rein yan jiu ((kong saur) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) yan hua rein yan jiu ((kong saur) OR (wong sau)) ;*.
