Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
you liang » you xian, you liangzhi
age child » age children
child der » child does, child did, child gender
yan guan » gan guan, yan yuan, yihan guan
der lang » der lange, der klang, der land
3 langer » 3 lange, 3 longer, 2 langere
langer a » longer a, lander a, langer _
lang 3 » klang 3, gang 3, lang _

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