Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
child weng » child went, child being, child well
yang yang » wang yang, wang yan
can child » care child, can build, can china
weng fang » jing fang, wen wang
longer do » longer _, long do
longer a » longer _
fang 3 » fang _, fang a, gang 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 liang) OR (yang yang)) can child weng fang 3 ((longer do) OR (longer a)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang yang)) can child weng fang 3 ((longer do) or (longer a)) ;*.
