Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
age child » age children
child wen » child went, child when, child well
longer a » longer _
klang 3 » klang 31, klang _, klange _
lang 3 » gang 3, lang _, lang a

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