What are the ancient modes of transportation?

In ancient China, boats were the main modes of transportation in the south and horses in the north. The reason is that the climate in the south is humid, the precipitation is abundant, and the surface river network is densely covered, so the ship transportation adapted to the "water town" came into being. In the north, however, the climate is arid and semi-arid, grasslands are widely distributed and animal husbandry is developed. In addition to providing milk and meat products, horses have been domesticated as vehicles by the people in the north and become vehicles on the land in the north because of their good endurance and high speed.
