Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
than china » tuan china, han china, wuhan china
hui ying » huei ying, hoi ying, hui ping
lei kyun » lee kyung, lee kyu, pei yun
de long » de longue
le long » life long, live long
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)) than china ((hui ying) OR (lei kyun)) ((de long) OR (le long)) du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang guang)) than china ((hui ying) or (lei kyun)) ((de long) OR (le long)) du ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yang guang)) than china ((hui ying) or (lei kyun)) ((de long) OR (le long)) du ;*.
