Perhaps you should try some spelling variations:
yang time » long time, yang jie, lag time
time lost » time cost, time loss, time list
thin lens » thin end
thin line » think like
dong skin » dong sin, dong bin, dof skin
yan yang » yang yang, yao yang, dan yang
wai yan » wang yan, wei 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 time lost ((thin lens) OR (thin line)) dong skin ;~.
• Adding a wildcard symbol may retrieve word variants: wai yan yang time lost ((thin lens) or (thin line)) dong skin ;*.
