What treaty did Song Zhenzong sign with the Liao Kingdom?

There was no specific name for the treaty when negotiating peace, only the name of the historical event "Chanyuan Alliance".

Song and Liao were countries of brothers. Shengzong of Liao was young and called Song Zhenzong his brother, and later generations still talked about him in this way.

The Song and Liao used the Baigou River as the boundary (the Liao abandoned Suicheng and the three prefectures of Zhuo, Ying, and Mo), and both sides withdrew their troops; thereafter, any thieves and fugitives who crossed the border were not allowed to stay in each other; the two dynasties along the border cities, Everything is as usual, no city god can be built.

The Song Dynasty provided Liao with 100,000 taels of silver and 200,000 pieces of silk every year to "support the military and brigade", which were delivered to Xiongzhou.

The two sides set up sales offices at the border to carry out mutual trade.
