Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
der klange » der lange, der klasse, der langen
can child » care child, can build, can china
child der » child does, child did, child gender
klange 3 » klange _, klang 3, change 3
3 longer » _ longer, 2 longer, 3 langer
longer a » longer _

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 yanling))) OR (yang guang)) can child der klange 3 longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) or (wang yanling))) or (yang guang)) can child der klange 3 longer a ;*.
