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 klang » den klang, der klang, en klant
2 longer » _ longer, 3 longer, a longer
longer a » longer _
klang 2 » klang 3, klang _, klarung 2

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 klang 2 longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) or (wang yang))) or (yang guang)) can child wen klang 2 longer a ;*.
