China is grappling with extreme weather conditions as strong winds and sandstorms sweep through the northern regions, particularly Beijing. Hundreds of flights have been cancelled, and millions of residents are advised to stay indoors, with authorities warning that those weighing less than 110 lbs could be at risk of being blown away. Parks have been closed, classes suspended, and transportation services disrupted due to the severe gales, which have prompted the issuance of first-level wind warnings not seen in a decade. The chaotic weather is attributed to a cold vortex from Mongolia, leading to some of the strongest winds in decades. As the situation develops, safety remains a top priority for both officials and residents.
