Perhaps you should try some spelling variations:
yang time » long time, yang jie, lag time
time last » time list, time past, time lost
last thin » last thing, last things
zeng dong » zeng doug, zheng rong, zheng cong
jeng dong » eng hong, zeng doug
yan yang » yang yang, yao yang, dan yang
wan yan » wang yan, nan yan, wai yan
sin » sign, sind, skin

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang time last thin ((zeng dong) OR (jeng dong)) sin ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yang time last thin ((zeng dong) OR (jeng dong)) sin ;*.
