Perhaps you should try some spelling variations:
wei daten » bei daten, der daten, ii daten
when food » when good
food eric » food price, food ethic
dong wei » wang wei, dong di, dong hoi
daten ii » daten iii, daten im, daten vi
yang jui » yang judy, yang yi
ying jin » yang jin, jing ji, yang jie
ii when » xxii when, ii where, ii wesen
yang xi » yang yi

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 wei daten ii when food eric ((((yang jui) OR (ying jin))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong wei daten ii when food eric ((((yang jui) or (ying jin))) or (((yang di) or (yang xi)))) ;*.
