How to treat the coexistence of Xia and Northern Song Dynasties in western Liaoning? Please talk about your opinion?

Liao, Xixia and Song San first appeared. In 9 16, the leader of the Khitan nationality, Baoji, proclaimed himself emperor in Beijing and established the Khitan State. Qidan changed its name many times and called it Liao for the time being. In 960 AD, Zhao Kuangyin, a general of the Zhou Dynasty, launched a mutiny in Chen Qiao and established the Northern Song Dynasty. 1038, Yuan Hao, the party town of Xia Wang, proclaimed himself emperor and established Xixia. Liao and Song lived side by side. In the Northern Song Dynasty, in order to recover the sixteen states of Youyun, which were cut to Qidan by the late Jin emperor Shi Jingtang, they fought against Liao twice and failed, so they had to take the defensive. However, Liao was worried about Song's Northern Expedition. 1004, and Song took offensive action. As a result, due to the efforts of Prime Minister Kou Zhun, the emperor really signed a clan, which encouraged Song Jun's morale and beat back the Liao army. 1005, the two sides made peace and signed a Covenant. Since then, the two sides have turned from war to peace, and the people of both sides have lived a better life. The relationship between Xixia and Song Dynasty is also war and peace. First, after Yuan Hao proclaimed himself emperor, he launched an anti-Song war. Both sides suffered great losses. Hao Yuan proposed peace talks, 1044, and the two sides reached peace talks. Since then, the trade between the two sides in the border areas has not only enriched the lives of the two peoples, but also greatly promoted the progress and development of Xixia. Looking at the relationship between Liao, Xixia and Song, the war was short-lived, and people of all ethnic groups got along well with each other was the mainstream of ethnic relations at that time. The hard work of Liao and Xixia people in the north of China not only developed the northeast, north and northwest of China, but also created rich national cultures, which made indelible contributions in the history of our country. It can be seen that the civilized history of our motherland was jointly created by the people of all ethnic groups in our country.
