The earliest trip

The pioneer of tourism is businessmen, and the earliest tourists are the Phoenicians, a maritime nation.

As a social behavior, tourism has existed since ancient times. China is one of the ancient civilizations in the world, and the rise of travel activities is also in the forefront of the world. China existed as early as the 22nd century BC. At that time, the most typical traveler was probably Dayu, who traveled all over the country in order to dredge the eighteen rivers in Jiujiang. Then came Laozi and Confucius in the Spring and Autumn Period and the Warring States Period.

Lao Tzu preached and rode the green ox west. Confucius gave lectures and traveled around the world. During the Han Dynasty, Zhang Qian went to the Western Regions as far away as Persia and now Iran and Syria. In the Tang Dynasty, Xuanzang learned the scriptures and went to India. In the Ming Dynasty, Zheng He made seven voyages to the West and reached the East African coast as far as possible. The great traveler Xu Xiake made a travel note.
