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, 3 langer, a longer
2 longer » _ longer, a longer, 2 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 (2 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 longer) OR (2 longer)) a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang liang)) age child wen lang ((3 longer) OR (2 longer)) a ;*.
