What's the significance of building a carriage in the west of Xia Dynasty?

Vehicles have served mankind for thousands of years. In the early years of Xia Dynasty in China, Xi Zhong built wooden vehicles drawn by horses in the snow, and was called the originator, god and saint of making cars by later generations.

The carriage invented by Xi Zhong is a great innovation in the ancient history of science and technology in China. It not only solved the backward traffic problem in ancient times, but also promoted the development of road facilities and social economy, expanded commercial traffic and cultural exchange activities, and laid the foundation for social development.
