A huge cloud of sand fell over Gansu province in northwest China.
The latter completely swallowed homes, buildings and factories, causing pollution and road accidents.
This impressive weather phenomenon is frequent in the northern part of the country in spring.
The yellow cloud observed this Sunday in Linze County was immortalized from the sky, giving the measure of the event.
Residents called to stay at home with windows closed
National television CCTV reported several accidents due to poor visibility.
Meteorologists have called on residents to stay at home with windows closed, with other similar phenomena expected on Tuesday.
Sandstorms that occur in the country often originate in the Gobi Desert, a huge sandy expanse spread between China and Mongolia.
Reforest to create a "great green wall"
In March, one of them reached Beijing, the strongest in a decade to strike the capital.
The skies had turned yellow, air pollution had surged and airlines had been forced to cancel hundreds of flights.
To curb these storms, the authorities have been reforesting the peripheral areas of the deserts for several decades, in order to create a "Great Green Wall" intended to block the sand.
