Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
can child » care child, can build, can china
child wen » child went, child when, child well
wen wang » wei wang, chen wang, weng fang
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 liang) OR (yang guang)) can child wen wang ((3 longer) OR (2 longer)) do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yang guang)) can child wen wang ((3 longer) OR (2 longer)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang guang)) can child wen wang ((3 longer) OR (2 longer)) do ;*.
