Perhaps you should try some spelling variations:
gain yang » dan yang, tan yang, yin yang
daun yang » dan yang, du yang, tan yang
lang yan » wang yan, wang yang, zhang yan
yan guan » gan guan, yan yuan, yang guang
kang hay » eang hay, kang han, kang tae
yan yan » yan yuan, nan yan, yang yang
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: lang yan yan guan ((gain yang) OR (daun yang)) jui ((kang hay) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yan guan ((gain yang) OR (daun yang)) jui ((kang hay) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yan guan ((gain yang) OR (daun yang)) jui ((kang hay) or (dang hai)) ;*.
