Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
wang zhang » wang zheng, wang luhang, zhang zhang
zhang ping » zhang ming, zhang jing, zhang ting
risk tong » risk among, risk along
can cost » can costa, can lost, chain cost
can post » can lost, can past, can postal
tong hui » wang hui

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang zhang ping ((can cost) OR (can post)) sharing risk tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: wang zhang ping ((can cost) OR (can post)) sharing risk tong hui ;*.
