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 dong » jeng dong, zeng doug, zheng rong
dong ping » dong sin, dong bin, dong jung
yan yang » yang yang, dan yang, tan yang
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: wai ((yan yang) OR (yao yang)) ((time last) OR (some past)) thin zeng dong ping ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((yan yang) OR (yao yang)) ((time last) or (some past)) thin zeng dong ping ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((yan yang) OR (yao yang)) ((time last) or (some past)) thin zeng dong ping ;*.
