Erected directly behind the Bird's Nest site, the huge display device carries the creative expression of "the water of the Yellow River comes from heaven", and inside the opening ceremony team, many people called this screen an "ice waterfall". "From beginning to end, 'the water of the Yellow River rises from heaven' is a very core idea." Liu Jijun, deputy manager of the performance installation of the National Stadium Operation Team, recalled, "Initially, the director's idea was only a rough outline, he wanted a curtain, the size is expected to be 36 meters wide and 60 meters high. "But the technical team found it extremely difficult to demonstrate. The Bird's Nest is an open-air venue, interconnected inside and outside, and according to the progress of the opening ceremony, the curtain must be built and installed last October. In October, beijing often has strong winds, and the wind speed in the field is very high, and such a large curtain is likely to be torn.
After comprehensive calculation and analysis, combined with the director's creative needs, the size of the "Icefall" was determined to be 20 meters wide and 59.6 meters high, equivalent to the height of 20 floors, and the installation took more than two months. In the whole construction process, construction, machinery, sound, light, electricity and other majors should be combined with each other to overcome many difficulties, and the high-definition grille screen and security and redundant backup used in "Icefall" are the current cutting-edge topics.
"For the first time, when the foreign students who wanted to participate in the "Tribute to the People" session saw this performance on the side stage, they were all sighing 'Amazing'!" Looking back on the situation at that time, the director of the sub-scene, Tao Wenting, was still very excited, and with the cooperation of the images and installations, the international students simply believed that the ice and snow in front of them were real. In the interview, they marveled at the great power of Chinese science and technology, and now China really stands in the center of the world stage, and some people said that they must stay in China to work in the future. At that moment, as Chinese, we were really proud. ”
