As one of China’s largest science and technology museums, this project sets national records for the largest-span skybridge and the longest cantilever construction in a single building. The design integrates with the natural environment, minimizing its impact on the surrounding ecosystem. With its unique concept, cultural depth,and functional positioning, it enhances the city’s image and quality, offering citizens diverse spiritual experiences while serving important cultural exchange and social functions.The spatial planning focuses on openness and flexibility, balancing artistic presentation with environmental sustainability and safety. The iconic rotating art installation, inspired by a Möbius strip, presents a multidimensional view of human technological progress. Due to its unique shape, the installation’s uneven stress distribution requires high material strength and toughness. Designers and engineers used advanced structural analysis and simulations to ensure the optimal structural system and component dimensions, achieving a flawless result. Chang'an Cloud has become a new symbol of Xi'an’s urban development, contributing to the city’s role in the "Belt and Road" initiative
