Perhaps you should try some spelling variations:
sharing food » sharing hold, securing food, sharing covid
zhang jian » zhang fan, shang jin
chain data » chained data, main data, again data
xi zhang » li zhang, xiao zhang, bin zhang
can data » dan data, fan data, ocean data
can tata » can take, can tax
kong » long, hong, pong

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: xi zhang jian ((((can data) OR (chain data))) OR (can tata)) sharing food kong (sar OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "xi zhang jian ((((can data) OR (chain data))) or (can tata)) sharing food kong (sar or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: xi zhang jian ((((can data) OR (chain data))) or (can tata)) sharing food kong (sar or saur) ;*.
