How was Liao destroyed?

During the reign of Song Zhenzong and Zhao Heng, he pursued the politics of Huang Lao and did nothing. At that time, the Liao Dynasty often robbed and plundered at the junction of Song and Liao Dynasties, which eventually evolved into a large-scale invasion of Song Dynasty in 1004. Prime Minister Kou Zhun urged anti-Japanese. As a result, Song Zhenzong's personal expedition greatly boosted Song Jun's morale. He was at loggerheads with the Liao army under Zhoucheng, and the Liao army was forced to make peace. After several negotiations, the two countries successfully held peace talks.

During Zhao Yong's rule in Song Shenzong, he was determined to reform, and Wang Anshi, a famous reformist minister, was appointed as a political advisor. Wang Anshi's new law includes equal damage, young crops, exemption from service, Yishi, Jiabao, Ma Bao and other land taxes.

After Song Huizong and Evonne acceded to the throne, he indulged in pleasure and was indifferent to state affairs, leaving all government affairs to six thieves headed by Cai Jing. Song Huizong himself was overjoyed. When he saw that the Liao country was attacked, he sent envoys to discuss attacking the Liao country, and the Northern Song Dynasty was responsible for attacking Nanjing and Xijing of the Liao country. After the demise of Liao, the land was returned to Song. This is the maritime alliance. But in the Song Dynasty, the army was defeated, the population of Yanjing was plundered by nomadic people, and Yingshang, Pingping and Luanhe were captured.
