Perhaps you should try some spelling variations:
deng ziliang » zeng ziqiang, peng liang
yang yang » wang yang, wang yan
can ching » can china, can change, can things
ching wen » ching kwan, ching fein, ching hea
yang yao » wang yan, yang yi, yang fan
yang ka » yang fan
long do » long d, long du, longer do

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: ((deng ziliang) OR (yang yang)) can ching wen ((yang ka) OR (yang yao)) long do ;~.
• Adding a wildcard symbol may retrieve word variants: ((deng ziliang) or (yang yang)) can ching wen ((yang ka) or (yang yao)) long do ;*.
