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
langer do » langer _
longer do » longer _, longer a, long do
wen lang » wen wang
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 (yang liang)) age child wen lang 3 ((langer do) OR (longer do)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yang liang)) age child wen lang 3 ((langer do) OR (longer do)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang liang)) age child wen lang 3 ((langer do) OR (longer do)) ;*".
