yang jun » yang jui, pang jun, yang jin
hong ghi » zhong zhi, hong hai
yan zhi » yan zi, wang zhi
yan yi » yang yi, tan yi, yan zi

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 ((yan yi) OR (yan zhi)) hua gene yang jun ((hong g) OR (hong ghi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yan yi) or (yan zhi)) hua gene yang jun ((hong g) or (hong ghi)) ;*.
