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 den » child does, child did
den klang » der klang, den gang, en klant
a longer » _ longer, 2 longer, 3 longer
longer a » longer _
klang a » klang 3, klang _, lang a

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 den klang a longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) or (wang yang))) or (yang guang)) can child den klang a longer a ;*.
