Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yan liang » yang liang, wang liang, you liang
hui ying » huei ying, hui ping, hui yang
hoi ying » li ying
ka long » a long, day long
long d » long do, long du, 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 (yan liang)) ((yuan fei) OR (than china)) ((hui ying) OR (hoi ying)) ka long d ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yan liang)) ((yuan fei) or (than china)) ((hui ying) OR (hoi ying)) ka long d ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yan liang)) ((yuan fei) or (than china)) ((hui ying) OR (hoi ying)) ka long d ;*.
