Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang yanling
can child » care child, can build, can china
child wen » child went, child when, child well
wen wang » wei wang, chen wang, weng fang
3 longer » _ longer, 2 longer, 3 langer
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: ((((wang liang) OR (wang yang))) OR (yang guang)) can child wen wang 3 longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) or (wang yang))) or (yang guang)) can child wen wang 3 longer a ;*.
