Perhaps you should try some spelling variations:
huang yang » huang ying, huang chang, wang yang
jang yang » wang yang, yang yang, wang yong
ban guan » gan guan, bat guano, quan guan
yan guan » gan guan, yan yuan, yang guang
kang hay » kang han, dang hai, kang tae
eang hay » dang hai, kang han
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 ((ban guan) OR (yan guan)) ((jang yang) OR (huang yang)) xi ((kang hay) OR (eang hay)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((ban guan) or (yan guan)) ((jang yang) or (huang yang)) xi ((kang hay) OR (eang hay)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((ban guan) or (yan guan)) ((jang yang) or (huang yang)) xi ((kang hay) OR (eang hay)) ;*.
