gain yang » tan yang, yin yang
daun yang » du yang, tan yang, un yang
yang run » yang jun, yang yun, long run
dan yang » tan yang, wang yang, yang yang
kang hay » eang hay, dang hai, kang tae
kang han » kang chen, kong hang, zhang han

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 ying yang run ((((gain yang) OR (dan yang))) OR (daun yang)) xi ((kang hay) OR (kang han)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying yang run ((((gain yang) OR (dan yang))) or (daun yang)) xi ((kang hay) or (kang han)) ;*".
