Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
yan guan » gan guan, yang guang, yihan guan
yan yuan » fang yuan, nan yan, yan clan
yang gai » yang dali, yang di, yang jui
gai gang » ngai hang, ii gang, i gang
gang hai » dang hai, shang hai, eang hay
yan yun » yang yun, yan kun, yap yun
wang » wing, wan, lang

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 ((yan yun) OR (((yan yuan) OR (yan guan)))) gain yang gai gang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((yan yun) or (((yan yuan) or (yan guan)))) gain yang gai gang hai ;*.
