When did the Cold Food Festival disappear?

The Cold Food Festival has not disappeared,

Generally speaking, in the first day or two in Tomb-Sweeping Day, because the two festivals are similar, cold food and Qingming have been combined since the Tang Dynasty.

In the Ming and Qing Dynasties, Tomb-Sweeping Day directly absorbed the Cold Food Festival and became Tomb-Sweeping Day with many customs such as ancestor worship, outing and eating cold food.

Youth League is a traditional special food popular in the south of the Yangtze River, which originated in the Tang Dynasty. Since then, every household in the south of the Yangtze River has steamed many green groups, some of which are mainly used for ancestor worship.

The rest is stored as cold food and eaten to the full in those days when the fire is banned. Mix wormwood juice into glutinous rice flour, and then steam it with stuffing such as bean paste or lotus seed paste to make soft glutinous and fragrant green balls. The steamed green meatballs are very gratifying and can be eaten.

Sweet and delicate, the fragrance of wormwood gradually diffuses in the mouth. The continuous drizzle around Tomb-Sweeping Day moistened the fast-growing wormwood and became the best ingredient for making green balls. Moreover, wormwood has high nutritional value and can help the body eliminate moisture after eating.
