Perhaps you should try some spelling variations:
code during » care during, code using, role during
during risk » using risk, during crises, during crisis
yang lying » yang yang, yang jing, yang liang
wang liang » wang yang
lands code » land code
how stable » do stable, how scale, how state
how she » how some, how safe, how shih

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 ((yang lying) OR (wang liang)) lands code during risk ((how she) OR (how stable)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang lying) OR (wang liang)) lands code during risk ((how she) OR (how stable)) ;*.
