What is the origin of Sister Qingming?

It is said that it began with the "tomb sacrifice" ceremony of ancient emperors and generals, and later people followed suit and became a fixed custom of the Chinese nation to worship ancestors and sweep graves on this day.

Originally, the Cold Food Festival and Tomb-Sweeping Day were two different festivals. In the Tang Dynasty, the day of sweeping graves was designated as the Cold Food Festival. The name "Tomb-Sweeping Day" also comes from the Tomb-Sweeping Day atmosphere in the twenty-four solar terms of the China lunar calendar. 105 The first day after winter is Qi Tomb-Sweeping Day. Tomb-Sweeping Day gas * * * has 15 days. As it is Tomb-Sweeping Day, the time is after the vernal equinox. At this time, the winter has gone, the spring is full, the weather is fine, the fields are bright and clean, and the outside of nature shows great vitality.

It is an appropriate word to call this period "Qingming". One hundred and five days after beginning of winter, the solstice was called cold food. In the past, fire was forbidden and cold food was eaten, so it was also called "Cold Food Festival" and "No Smoking Festival". According to folklore, cold food is to commemorate Mianshan pushing mesons dry in the Spring and Autumn Period, and Jin Wengong ordered a fire ban.

Jiezitui is from Shanxi, so the custom of cold food is first popular in Shanxi. In the old days, cold food cut off fire, and the next day there was a ceremony to drill wood for fire in the palace, and the people also begged each other for fire with wicker.

Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
