Sichuan area is one of the earliest areas of ancient culture development in China. According to archaeological findings, primitive humans have been working, living and multiplying in this ancient land of Sichuan since 2.04 million years ago, and created the ancient Sichuan civilization with their own wisdom and hard-working hands. Sichuan has a recorded history of over 3000 years. During the Yin and Zhou Dynasties, two countries were established in Sichuan: one was the Shu State, which was centered on the ancient Shu State and established in today's western Sichuan; The other is Pakistan, which was established in eastern Sichuan (including Chongqing) with the Cuban nationality as the center. Therefore, Sichuan was called "Bashu" in ancient times. In 3 16 BC, after Qin came to Bashu, Sichuan became the area under the jurisdiction of various dynasties in China. Until the fourth year of Song Zhenzong Xianping (100 1), Sichuan-Shaanxi Road was divided into four roads, namely Yizhou, Zizhou, Lizhou and Kuizhou. Up to now, it has the name of "Sichuan", just 1000 years ago.
