We often read the Air Quality Index（空气质量指标）or AQI reported in the newspaper. The AQI helps us understand what the air quality around us means to our health. The AQI uses colors, numbers and words to tell us about the air. Let’s see what these colors and numbers mean.

AQI colors	AQI Numbers	Health word(s)	What to do
Green	0-50	Good	Just enjoy the clean air!
Yellow	51-100	Moderate (适中)	Air quality is fine for most people.
Orange	101-150	Unhealthy for sensitive(敏感的) groups	Active children and adults and people with lung(肺) disease should spend less time outdoors
Red	151-200	Unhealthy	People with lung disease and active kids and adults shouldn’t spend too long time outdoors. Everybody else should try to spend less time outside.
Purple	201-300	Very unhealthy	People with lung disease and active kids and adults should not spend any time outdoors. Everybody should try not to go outside.
