China's Spring Festival Rush Sets Single-Day Record

China's Spring Festival travel rush, known as chunyun, shatters records with 352.999 million cross-regional passenger trips on February 20, a 12.3 percent surge from last year. This monumental movement across rail, air, highway, and waterway networks underscores the world's largest annual human migration during the 40-day period from February 2 to March 13, projected to total 9.5 billion trips.
