Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
yan liang » yang liang, wang liang, you liang
tan china » tuan china, than china, can china
pei yang » wei yang, hui yang, yi yang
pei yun » lei kyun, mei yung, wei yuan
di long » i long, de long, ii long
long do » long d, long du, longer do

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: ((((yang yang) OR (yan liang))) OR (yang guang)) tan china ((pei yang) OR (pei yun)) di long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) or (yan liang))) or (yang guang)) tan china ((pei yang) OR (pei yun)) di long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (yan liang))) or (yang guang)) tan china ((pei yang) OR (pei yun)) di long do ;*.
