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
wen lang » wen wang
3 longer » _ longer, 2 longer, a longer
3 langer » 3 lange, 2 langere, b langere

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