Perhaps you should try some spelling variations:
kang hari » dang hai, kang han
yan guan » yan yuan, yang guang, yihan guan
gan guan » quan guan, fan guon, gui guan
yang yun » yang jun, tang yun, yang yue
yan kun » yan yuan
yang xi » yang di, yang yi, yang jui
xi kang » jin kang, xi zhang
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 kun) OR (((yan guan) OR (gan guan))))) OR (yang yun)) du yang xi kang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yan kun) or (((yan guan) OR (gan guan))))) or (yang yun)) du yang xi kang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yan kun) or (((yan guan) OR (gan guan))))) or (yang yun)) du yang xi kang hari ;*.
