Perhaps you should try some spelling variations:
child when » child went, child who, children when
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang
age child » age children
when lang » when large, when can, when any
3 longer » _ longer, 2 longer, 3 langer
longer a » longer _
lang 3 » klang 3, gang 3, lang _

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang yang) OR (wang yan))) or (yang liang)) age child when lang 3 longer a ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yan))) OR (yang liang)) age child when lang 3 longer a ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) OR (wang yan))) or (yang liang)) age child when lang 3 longer a ;*".
