Perhaps you should try some spelling variations:
hard things » hard thing, bad things, smart things
things here » things were, things era, things have
wang liang » wang yang
liang fang » jing fang, liang dan, liang tan
song bing » song ming, song byung, dong bin
fang 3.3 » jing 3.3
3.3 hard » 3.1 hard, 3.3 shared, 5.3.3 hard
tan yong » tan hong, tan kong, tan yang
dann bin » dong 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 fang 3.3 hard things here ((tan yong) OR (((song bing) OR (dann bin)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang fang 3.3 hard things here ((tan yong) or (((song bing) or (dann bin)))) ;*.
