1. Explanation of the ancient Shu Kingdom:

The ancestors of the ancient Shu people For the Shushan clan, some people believe that the Shushan clan and the Cancong clan arose from the upper reaches of the Minjiang River and are a branch of the ancient Qiang people. The Kingdom of Shu not only had a single dynasty, but before the Qin Dynasty destroyed Shu, Shu was ruled by the Cancong, Baiguan, Yufu, and Kaiming clans. Before the fifth generation of Kaiming, the capital of Shu was built in Fanxiang, Guangdu (today's Shuangliu County). In the ninth era of Kaiming, the capital was established in Chengdu. During the twelfth generation of the Kaiming Dynasty, the "Five Ding Lishi" opened up the Stone Cow Road and opened up the channel from Shu to Qin. In 316 BC, when King Qin Hui was on the throne, the State of Qin destroyed the State of Shu. From then on, Shu became the granary of the State of Qin, laying the foundation for Qin to unify the six kingdoms. After the Qin Dynasty destroyed Shu, the remnants of the Shu people, led by Prince Anyang King, moved southward, finally reaching Jiaozhi and established a new dynasty in what is now northern Vietnam, which lasted for more than a hundred years.
