Perhaps you should try some spelling variations:
care child » calle child, cause child, age child
you liang » you xian, you liangzhi
child der » child does, child did, child gender
yan guan » gan guan, yan yuan, yang guang
klang 31 » klang _, lang 3
langer a » longer a, lander a, langer _
klang 3 » klang _, lang 3, klange _

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: ((you liang) OR (yan guan)) care child der ((klang 31) OR (klang 3)) langer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((you liang) or (yan guan)) care child der ((klang 31) OR (klang 3)) langer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((you liang) or (yan guan)) care child der ((klang 31) OR (klang 3)) langer a ;*.
