Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
than china » tuan china, han china, wuhan china
yang yang » wang yang, wang yan
yan wang » yuan wang, qian wang, yan liang
jaan hui » yuan hui
pei yang » wei yang, hui yang, pei yun
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: ((((yan wang) OR (yang yang))) OR (yang guang)) ((jaan hui) OR (than china)) pei yang di long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan wang) OR (yang yang))) or (yang guang)) ((jaan hui) or (than china)) pei yang di long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yan wang) OR (yang yang))) or (yang guang)) ((jaan hui) or (than china)) pei yang di long do ;*.
