Perhaps you should try some spelling variations:
chained data » shared data
chain data » main data, again data, brain data
zhong zhi » zhang zhi, zhong tai
dong can » dong cao, dong nan, congo can
can save » can have
hong ghi » hong g, hong hai
wan min » wan ming, han min, kan min

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: dong can save ((chain data) OR (chained data)) wan min ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong can save ((chain data) OR (chained data)) wan min ((hong ghi) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong can save ((chain data) OR (chained data)) wan min ((hong ghi) or (zhong zhi)) ;*.
