Visitors can know the city from three perspectives: history of city development, scientific planning for the city, and an exploration of the city's future.

Additionally, the planning hall features China's first three-screen projection, which can project films on the roof, the wall, and the ground, through which visitors can experience a 3D version of future city life.

Visitors look at photos of people who contribute to the construction and development of Changchun. [Photo provided to chinadaily.com.cn]
