A special cultural activity was held at Hubin Pedestrian Street on February 21 to celebrate the 200-day countdown to Hangzhou Asian Games, which started right after Beijing closed the Winter Olympics. Introducing "Little Green Box" (souvenir for the volunteers), customized jade seal and personalized stamps, announcing the soliciting of Hangzhou Asian Games collections, encouraging mass sports cultural performances and UAV shows around the city… all these activities contributed to a great celebration full of Asian Games elements and powered up Hangzhou as an Asian Games city.
