Perhaps you should try some spelling variations:
last things » first things, smart things
douglas a » douglas f, douglas w
dan yang » daun yang, tan yang, wang yang
yang his » yang chik, yang di, yang xi
yang yi » yang di, yang xi, yang jui
things » thinks, thins
thing » think, thin
zeng » eng, feng, peng

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: dan yang ((yang his) OR (yang yi)) ((last things) OR (last thing)) zeng douglas a ;~.
• Adding a wildcard symbol may retrieve word variants: dan yang ((yang his) or (yang yi)) ((last things) or (last thing)) zeng douglas a ;*.
