Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
you liang » you xian, you liangzhi
lang yan » wang yan, wang yang, zhang yan
hui ping » hui ying, chui ling, hui sin
ping fa » ping jia
long du » long do, long run, long did
long d » long do, long _, long 2

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: ((lang yan) OR (you liang)) ((yuan fei) OR (than china)) hui ping fa ((long d) OR (long du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) or (you liang)) ((yuan fei) or (than china)) hui ping fa ((long d) OR (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (you liang)) ((yuan fei) or (than china)) hui ping fa ((long d) OR (long du)) ;*.
