(Clearwisdom.net) On the morning of April 7, just 5 days after the last sand storm on April 2, it hit Changchun City again. The sky became grayish and yellowish with very low visibility. There was a layer of yellow soil on the ground. There were few pedestrians on the street. Many people wore dust masks, including the workers in shops.

These photos were taken in Changchun's downtown commercial area around 12:30 p.m.
