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.

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. |
