What does it mean to start the three-level plan for heavy polluted weather in Chengdu?

The early warning of heavily polluted weather is divided into three levels from light to heavy: the third level early warning, the second level early warning and the first level early warning, which are marked with yellow, orange and red respectively, and the first level early warning (red) is the highest level.
Three-level early warning (yellow): In the next 72 hours, air quality index (AQI) will appear alternately in the range of 20 1~300 or air quality index (AQI) will appear alternately in the range of 20 1~300 and 30 1~500, and yellow pollution early warning information will be issued.
Secondary warning (orange): In the next 72 hours, the air quality index (AQI) will be within the range of 30 1~500, and orange pollution warning information will be released.
First-class warning (red): If the air quality index (AQI) is greater than 500 in the next 24 hours, red pollution warning information will be issued. [ 1]
