Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
can child » care child, can build, cbt child
longer do » longer _, long do
wen wang » wei wang, chen wang, weng fang
longer a » longer _
wang 3 » wang _, gang 3, lang 3

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: ((yan liang) OR (yang yang)) ((can child) OR (can china)) wen wang 3 ((longer do) OR (longer a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang yang)) ((can child) OR (can china)) wen wang 3 ((longer do) or (longer a)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang yang)) ((can child) OR (can china)) wen wang 3 ((longer do) or (longer a)) ;*.
