Perhaps you should try some spelling variations:
liang zwang » xiliang zhang
xiang zhong » xiliang zhang
hard things » hard thing, bad things, smart things
things make » things image, things have, settings make
3.2 hard » 2.2 hard, 3.1 hard, 3.3 hard
tan yong » tan hong, tan kong, tan yang
dong bin » dong sin, dong di, dann bin

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) OR (xiang zhong)) 3.2 hard things make ((tan yong) OR (dong bin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((liang zwang) or (xiang zhong)) 3.2 hard things make ((tan yong) or (dong bin)) ;*.
