Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
tan chia » tuan china, than china, can china
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan
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.

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