Strolling through the streets of Beijing, we can see that traditional architecture and modern architecture complement each other, with both cultural characteristics and the style of the times.

Modern buildings have sprung up like mushrooms after rain, the urban area has been expanding, and urban infrastructure and public services have been greatly improved.
