Perhaps you should try some spelling variations:
peng liang » wang liang, yang liang, deng ziliang
yang yang » wang yang, wang yan
can child » care child, can build, cbt child
wen wang » wei wang, chen wang, weng fang
long du » long d, long run, long did
long do » long d, longer do, long ago
wang a » wang _, fang a, lang a

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: ((peng liang) OR (yang yang)) ((can child) OR (can china)) wen wang a ((long du) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((peng liang) or (yang yang)) ((can child) or (can china)) wen wang a ((long du) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((peng liang) or (yang yang)) ((can child) or (can china)) wen wang a ((long du) OR (long do)) ;*.
