It is described as "the largest tent in the world." Under the tent, which is larger than 10 football stadiums, is an urban entertainment and shopping center with plazas and cobblestone streets, stores, a mini golf course, a flowing river, and a beach. The roof is made of transparent ETFE plastic, providing access to the sun's rays, which, combined with an air heating and air conditioning system, allows the indoor temperature to be maintained between 15-30 degrees C in the main space and 19-24 degrees C in the shopping mall. Outdoor temperatures throughout the year range from -35 to +35 degrees C.
