In the fourth year of the Qianfu reign of Emperor Xizong of the Tang Dynasty, the Huangchao Uprising broke out, the Tang Dynasty collapsed, the vassal towns were completely out of control, the Yanyun border was left unattended, and the era of disorderly mixing of Hu and Han began. During the Xianping period of the Northern Song Dynasty, Song Taizong's two large-scale Northern Expeditions completely failed. The Song army gave up the initiative to regain Yanyun. The confrontation between the north and the south of Song and Liao was permanently solidified. On the eve of the Chanyuan Alliance, the dust of a century of chaos settled. Span: 120 years, a border village, and the new journey of four generations. It embodies the theme of "the Han Dynasty is not all good, and the Hu is not all evil", and China is never a territorial origin, but the good and evil of people's hearts. Big history is reflected in the life of a small person, and people's hearts can be seen between reality and reality.
