Editor's note: A huge steel lotus bloomed in Zhangjiajie, Hunan Province, on Sept. 5 as developers there went through trial runs of a building's retractable dome, the largest of its kind in the world. Designed to mimic the lotus flower, the dome is made up of 10 pieces of steel weighing a total of 500 tons and takes nearly 10 minutes to open and come together again. The building, which has already become a landmark of the city, will officially open to the public on Sept. 10. Covering a construction area of 21,000 square meters, it will become the world's largest bar with cultural and leisure facilities that can accommodate 3,800 people.
