Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yang guang » yang yang, yan guan, yang liang
tan chia » tuan china, can china, dan china
pei yun » lei kyun, mei yung, pei yang
de long » le long, de longue
long du » long d, long do, long run
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) OR (yang guang)) ((tan chia) OR (than china)) ((du yang) OR (pei yun)) de long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang guang)) ((tan chia) OR (than china)) ((du yang) or (pei yun)) de long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yang guang)) ((tan chia) OR (than china)) ((du yang) or (pei yun)) de long du ;*.
