@beijingchina_066: Shanghai empties out once a year 🧧 Chinese New Year — millions of workers travel home to their home provinces, and the city genuinely goes quiet 😳 It's part of chunyun, the largest annual human migration on Earth. Billions of trips in a few weeks 🚄 Meanwhile Yu Garden fills with lanterns, and the skyline goes red and gold 🏮 The emptiest and most beautiful week of the year 📍 #shanghai #china #chinatravel #chinesenewyear #lanternfestival #yugarden #travel
