Did Dali allow Han Chinese to enter the country during the Song Dynasty?

I suggest you read the History of the Song Dynasty, or the Nanman chapter in Sima Guang's Zi Tong Zhi Jian, specifically introducing the relationship between Dali Kingdom and the Song Dynasty. In fact, there was no big war with Dali local government during the Song Dynasty, but there were more trade exchanges. Dali's Malangzi Sword is very famous and exported to Song, Xixia and Tubo. High school has a special introduction to the ancient history of China. Therefore, the Han people's entry into Dali can be traced back to the beginning of the "Kaiwuchi Road" in the Qin Dynasty.
