Perhaps you should try some spelling variations:
hard things » hard thing, bad things, smart things
things here » things were, things era, things have
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
5.2 hard » 2.2 hard, 5.2 shared, 5.2 charm
tan yong » tan hong, tan kong, tan yang
sin » sign, sind, skin

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 ((yang liang) OR (yang yang)) 5.2 hard things here ((tan yong) OR (dong sin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang liang) or (yang yang)) 5.2 hard things here ((tan yong) or (dong sin)) ;*.
