Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
yan guan » gan guan, yan yuan, yang guang
yan yun » yan yuan, yang yun, yap yun
yan kun » yan yuan
yang ii » yang di, yang xi, yang yi
ii dang » ii ding, ii doing
wang » wing, wan, lang
hai » hadi, haji, hari

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 hyoung ((yan yun) OR (((yan kun) OR (yan guan)))) gain yang ii dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung ((yan yun) or (((yan kun) or (yan guan)))) gain yang ii dang hai ;*.
