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