Perhaps you should try some spelling variations:
during labor » using labor, during last, during low
risk during » risks during, risk using, crisis during
labor along » laboring along
along shu » along nhue, cong shu, along who
can risk » chain risk
yan zhi » wang zhi
yang yi » yang di, yang xi, yang jui
yan zi » yuan zi, ban zi

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: wing ((((yan zi) OR (yan zhi))) OR (yang yi)) can risk during labor along shu ;~.
• Adding a wildcard symbol may retrieve word variants: wing ((((yan zi) or (yan zhi))) or (yang yi)) can risk during labor along shu ;*.
