"Beijing engulfed by massive sandstorm"

Si:

Fine dust particles and sand swept in from the Gobi Desert caused the AQI readings in Beijing to soar as high as 905, a ludicrously high level even for Beijing. In China's rather lenient air quality rating system, readings of over 300 are considered "hazardous" with residents warned to avoid "all outdoor exertion." Beyond that, readings simply go "beyond index."
