Perhaps you should try some spelling variations:
time last » time list, time past, time lost
some past » some case, time past
thin zeng » thin end, thin lens
zeng doug » jeng dong, zeng douglas
doug ping » dong ping, dou peng
yang yao » yang yang, wang yan, yang yi
yao yang » yang yang

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 yao yang ((time last) OR (some past)) thin zeng doug ping ;~.
• Adding a wildcard symbol may retrieve word variants: yang yao yang ((time last) or (some past)) thin zeng doug ping ;*.
