Perhaps you should try some spelling variations:
states during » rates during, states using, states making
small states » small scale
during dea » during data, during a, during new
yang yang » wang yang, wang yan
yu fang » yu gang, yu wang, yu yang
dea bei » der bei, drag bei
land a » land _, poland a

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: ((yang yang) OR (yu fang)) land a small states during dea bei ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yu fang)) land a small states during dea bei ;*.
