Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, yin yang
tan yang » dan yang, tan ying, tan yong
yi chang » ii chang, ying chang, jin chang
wan yan » wang yan, nan yan, wai yan
yan yun » yan yuan, yang yun, yap yun
yan kun » yan guan, yan yuan
i gang » ii gang, li gang, yi gang

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: wan yan ((yan yun) OR (yan kun)) ((gain yang) OR (tan yang)) ((yi chang) OR (i gang)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((yan yun) or (yan kun)) ((gain yang) or (tan yang)) ((yi chang) or (i gang)) hai ;*.
