Perhaps you should try some spelling variations:
liang zwang » xiliang zhang
hard things » hard thing, bad things, smart things
wang liang » wang yang
things era » things here, things were, things a
zwang 3.2 » zwang 2.2
dong sind » dong sin, dong bin, dong ping
3.2 hard » 2.2 hard, 3.1 hard, 3.3 hard
tan yong » tan hong, tan kong, tan ying
tan yang » dan yang, tan ying, tao 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: wang liang zwang 3.2 hard things era ((((tan yong) OR (tan yang))) OR (dong sind)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang zwang 3.2 hard things era ((((tan yong) or (tan yang))) or (dong sind)) ;*.
