Perhaps you should try some spelling variations:
huang lying » huang ying, huang jing, huang lin
code during » care during, code using, role during
during risk » using risk, during crises, during crisis
wang huang » wang luhang, wang hua, wang liang
lying land » lying lands, sloping land, linking land
how stable » do stable, how scale, how state
land code » land cover
how safe » how safety, how space, how scale
how she » how some, how shih

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 huang lying land code during risk ((((how she) OR (how safe))) OR (how stable)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang huang lying land code during risk ((((how she) OR (how safe))) or (how stable)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang huang lying land code during risk ((((how she) OR (how safe))) or (how stable)) ;*.
