Perhaps you should try some spelling variations:
past things » last thing, first things, smart things
last things » last thing, first things, smart things
yang time » long time, yang jie, lag time
dong skin » dong sin, dong bin, dof skin
yan yang » yang yang, yao yang, dan yang
dong wei » wang wei, dong di, dong hoi
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 ((past things) OR (last things)) during ((dong skin) OR (dong wei)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang time ((past things) OR (last things)) during ((dong skin) or (dong wei)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang time ((past things) OR (last things)) during ((dong skin) or (dong wei)) ;*.
