Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
can child » care child, can build, can china
child der » child does, child did, child gender
der klang » der klange, den klang, des klangs
yan guan » gan guan, yan yuan, yang guang
3 longer » _ longer, 2 longer, 3 langer
longer a » longer _
klang 3 » klang 31, klang _, 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: ((yan liang) OR (yan guan)) can child der klang 3 longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yan guan)) can child der klang 3 longer a ;*.
