Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yan liang » yang liang, wang liang, you liang
hui ping » hui ying, chui ling, hui sin
wan yan » wang yan, nan yan, wai yan
long do » long du, longer do, long ago
ping a » ping fa, ping _, coping a
long d » long du, 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: ((wan yan) OR (yan liang)) ((yuan fei) OR (than china)) hui ping a ((long d) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (yan liang)) ((yuan fei) or (than china)) hui ping a ((long d) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (yan liang)) ((yuan fei) or (than china)) hui ping a ((long d) OR (long do)) ;*.
