China has issued an urgent warning for millions to stay indoors this weekend as powerful winds are set to sweep across the country. Reports indicate that wind speeds could reach up to 150 kilometers per hour, strong enough to lift people weighing less than 50 kilograms off the ground. The dangerous weather, driven by a cold vortex from Mongolia, is expected to impact Beijing, Tianjin, and parts of Hebei province. For the first time in a decade, Beijing has raised an orange alert for windstorms, the second-highest warning level, highlighting the serious threat to public safety.
