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