Perhaps you should try some spelling variations:
huang yang » huang ying, huang chang, wang yang
jang yang » wang yang, wang yong, dan yang
yang yang » wang yang
gan guan » yan guan, quan guan, fan guon
kang hay » eang hay, kang han, dang hai
yan gan » yan guan, yan clan, yan wang
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 gan guan ((((jang yang) OR (yang yang))) OR (huang yang)) xi kang hay ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan gan guan ((((jang yang) or (yang yang))) or (huang yang)) xi kang hay ;*.
