Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
time last » time list, time lost, time class
time past » time part, time pad, some past
thin zeng » thin end, thin lens
zeng doug » jeng dong, zeng douglas
yan yang » yao yang, dan yang, tan yang
doug bin » dong bin, dort bin, org bin

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