Perhaps you should try some spelling variations:
cost during » boost during, crust during, west during
during risk » using risk, during crises, during crisis
risk tong » risk among, risk along
yang jui » yang judy, yang di, yang xi
ying jin » yang jin, jing ji, yang jie
tong hui » wang hui
wang » wing, wan, lang

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: wang yan ((((pang jun) OR (yang jui))) OR (ying jin)) cost during risk tong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((pang jun) OR (yang jui))) or (ying jin)) cost during risk tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((pang jun) OR (yang jui))) or (ying jin)) cost during risk tong hui ;*.
