Is Tomb-Sweeping Day a festival where the Qing Dynasty and the Ming Dynasty merged?

This can be thought of.

Tomb-Sweeping Day is not only one of the 24 solar terms, but also a traditional festival with a long history. The day before in Tomb-Sweeping Day was called Cold Food Festival. The two festivals coincide with the spring of March, with bright spring, pink and green, and a thriving atmosphere. The establishment of the Cold Food Festival is to commemorate the intermediary of the Jin Dynasty in the Spring and Autumn Period that "it is unfair to burn people to death". During the Qingming cold food period, there were folk customs such as forbidding fire and cold food, worshipping ancestors and sweeping graves, and going out for an outing. There are also traditional activities such as swinging, flying kites, tug-of-war, cockfighting, willow crossing, weeding and ball games. Let Qingming become a poetic festival. Sacrificing ancestors to sweep graves in Ming Dynasty is a traditional folk custom in Wuxi. Pick some new tombs when sweeping graves. Every new grave must be swept before Qingming; Old graves can be cleared, but not in the long summer. The new wife must go to the ancestral grave, commonly known as the "flower grave". When sweeping the grave, use vegetarian food, wine and rice to pay homage. Later, it was replaced by dried fruit cake.
