Introduction to the Chongqing Pavilion of the China Joint Pavilion: The exterior shape of the pavilion is abstractly deformed with the elements of "Kuimen World Hero" and the steep mountain peaks of the mountain city, highlighting the urban form of "surrounded by two rivers, a mountain within the city, and a city within the mountain". The exhibition hall is mainly divided into three exhibition areas: Born Chongqing, Humanistic Chongqing, and Miracle Chongqing, and two interactive experience areas: new energy 4D experience, intangible cultural heritage and high-tech demonstration. It interprets the changes of the city by sorting out Chongqing's ecological footprint, humanistic footprint and urban footprint. . The exhibition hall uses "Livable Chongqing", "Smooth Chongqing", "Forest Chongqing", "Safe Chongqing" and "Healthy Chongqing" to show Chongqing's new economic growth mode and the beautiful vision of building a mountain forest city system.
