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, song jin
fang 3.3 » jing 3.3
3.3 hard » 3.1 hard, 3.3 shared, 5.3.3 hard
tan yang » dan yang, tan ying, tan yong
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 fang 3.3 hard things here ((tan yang) OR (((song bing) OR (dong bin)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang fang 3.3 hard things here ((tan yang) or (((song bing) or (dong bin)))) ;*.
