Beijing is facing severe pollution levels and has witnessed the rare phenomenon of a “blue sun.”

At 6:00 on February 21, the Beijing Central Meteorological Observatory continued to issue a yellow alert for sandstorms.

Today, the Central Meteorological Observatory continued to issue yellow alerts for strong winds and sandstorms, a blue alert for heavy snow, and a blue alert for cold wave.

In the afternoon, Beijing experienced windy weather accompanied by sand blowing, leading to significantly reduced visibility in the city.

The entire city of Beijing is under a yellow alert for strong winds and a blue alert for sandstorms. The area of strong winds continues to move eastward, affecting most parts of the city.

The topic of “Beijing sandstorms” trended on social media. Many videos uploaded by netizens showed a grey sky and strong winds blowing sand in Beijing.

According to Beijing Daily, visibility in Beijing decreased on Saturday afternoon, with the sky appearing hazy and the sun emitting a faint blue light. In western areas, visibility ranged from two to four kilometers.
