Tomb-Sweeping Day in Song Dynasty? What is the evidence?

Qingming was just the name of a solar term at first, and later became a festival to commemorate ancestors, which was related to the Cold Food Festival. Jin Wengong designated the second day of the Cold Food Festival as Tomb-Sweeping Day. In most parts of Shanxi, the day before Tomb-Sweeping Day was the Cold Food Festival. Tomb-Sweeping Day in Yushe County and other places celebrated the Cold Food Festival two days ago; Yuanqu County also pays attention to Tomb-Sweeping Day's Cold Food Festival the day before, and the light cold food the day before.

Tomb-Sweeping Day first appeared in the Spring and Autumn Period, so it can be judged that there was Tomb-Sweeping Day in the Song Dynasty.
