Perhaps you should try some spelling variations:
during risk » during crises, during crisis, reducing risk
using risk » using rs, funding risk, rising risks
und neuer » und neue, und neuen, und neues
wang dan » wang yan, wang ban, wang yidan
dan rang » dan yang, dan dana, dan qing
rang und » gang und, lang und, wang und

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 dan rang und neuer ((during risk) OR (using risk)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan rang und neuer ((during risk) OR (using risk)) cong shu ;*.
