Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
can lost » can lose, can post, can boost
can cost » can costa, can post, chain cost
wan yan » wang yan, nan yan, wai yan
yang mu » yang muxi, yang jui, yang jun
yang du » yang di, yang d, yang jui
yan zi » yan zhi, yuan zi, ban zi

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan zi ((((can lost) OR (can cost))) or (von karl)) sharing risk ((yang mu) or (yang du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan zi ((((can lost) OR (can cost))) OR (von karl)) sharing risk ((yang mu) OR (yang du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan zi ((((can lost) OR (can cost))) or (von karl)) sharing risk ((yang mu) or (yang du)) ;*".
