Perhaps you should try some spelling variations:
yanling yang » ying yang
sharing risk » sharing best, during risk
yang yang » wang yang, wang yan
among hui » among heis, among eu, tong hui
can cost » can costa, can post, chain cost
can lost » can lose, can post, can boost
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 ((yanling yang) OR (yang yang)) ((can cost) OR (can lost)) sharing risk among hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yanling yang) OR (yang yang)) ((can cost) or (can lost)) sharing risk among hui ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yanling yang) OR (yang yang)) ((can cost) or (can lost)) sharing risk among hui ;*.
