Perhaps you should try some spelling variations:
hard things » hard thing, bad things, smart things
wang liang » wang yang
dong yang » dong hoang, wang yang, yang yang
3.3 hard » 3.1 hard, 3.3 shared, 5.3.3 hard
things a » things _, things 1
dann bin » dong bin
lag 3.3 » fang 3.3, slag 3.2, slag 3.4

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 yanling lag 3.3 hard things a ((wang liang) OR (((dong yang) OR (dann bin)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yanling lag 3.3 hard things a ((wang liang) or (((dong yang) or (dann bin)))) ;*.
