Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
tan chia » tuan china, than china, can china
hui yang » hui ying, h yang, hui ping
pei yun » lei kyun, mei yung, pei yang
de long » le long, de longue
long du » long d, long do, long run

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (yang guang)) tan chia ((((hui yang) OR (du yang))) or (pei yun)) de long du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yang guang)) tan chia ((((hui yang) OR (du yang))) OR (pei yun)) de long du ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang guang)) tan chia ((((hui yang) OR (du yang))) or (pei yun)) de long du ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang guang)) tan chia ((((hui yang) OR (du yang))) or (pei yun)) de long du ;*.
