chang ban » change bad, chang ha, chang mae
hua rene » juan rene
hua ren » hua chen
jing ji » ying jin
yang yi » yang di, yang jui
yang xi » yang di, yang jui
hong yu » wong yue

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: yuan chang ban ((hua rene) OR (hua ren)) ((jing ji) OR (((yang yi) OR (yang xi)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan chang ban ((hua rene) OR (hua ren)) ((jing ji) or (((yang yi) or (yang xi)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: yuan chang ban ((hua rene) OR (hua ren)) ((jing ji) or (((yang yi) or (yang xi)))) hong yu ;*.
