Perhaps you should try some spelling variations:
sharing oil » sharing big, sharing his, sharing covid
sharing our » shaping our, sharpening our
run risk » sun risk, crbn risk, own risk
can risk » chain risk
can shu » can she, tan shu, cong shu
yan yi » yang yi, tan yi, yan zi
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 yi ((run risk) OR (can risk)) ((sharing oil) OR (sharing our)) can shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yi ((run risk) or (can risk)) ((sharing oil) OR (sharing our)) can shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yi ((run risk) or (can risk)) ((sharing oil) OR (sharing our)) can shu ;*.
