Chinese cities have a history of at least five thousand years, and the city of Chang'an in the Tang Dynasty is a milestone. The planning and design of Chang'an City represented the most advanced level in the world at that time and laid the foundation for the design of China's capital city. With the global outbreak of the new crown virus COVID-19, it is even more necessary to enter the "post-epidemic era" for urban epidemic prevention and governance measures.
