Perhaps you should try some spelling variations:
things adding » thing adding, things using, things expanding
things during » things using, things sharing, thing hiring
zhang yan » zhang fan, zhang jian, wang yan
yan yang » yang yang, yao yang, dan yang
di first » ai first, d first, i first
dong » doing, long, done
sin » sign, sind, skin

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: zhang yan yang di first ((things adding) or (things during)) dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yan yang di first ((things adding) OR (things during)) dong sin ;.
• Adding a wildcard symbol may retrieve word variants: zhang yan yang di first ((things adding) or (things during)) dong sin ;*.
