Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
meng yuan » meng hsuan, fang yuan, feng juan
one vast » one last, one fast, one case
vast day » fast days
how cool » how school, how could, how cios
ying jin » yang jin, jing ji, yang jie
day how » days how, way how, say how
yang yi » yang xi, yang jui

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: one vast day how cool ((((ying jin) OR (yang yang))) OR (yang di)) ((meng yuan) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: one vast day how cool ((((ying jin) or (yang yang))) or (yang di)) ((meng yuan) or (yang yi)) ;*.
