Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
than china » tuan china, han china, wuhan china
yang yang » wang yang, wang yan
ka longer » a longer, _ longer, 2 longer
longer do » longer _, longer a, long do
hui ying » huei ying, hui ping, hui yang
hoi ying » li ying

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: ((yang liang) OR (yang yang)) than china ((hui ying) OR (hoi ying)) ka longer do ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang yang)) than china ((hui ying) or (hoi ying)) ka longer do ;*.
