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
yan yang » yang yang, yao yang, dan yang
wang » wing, wan, lang

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