Who is Tomb-Sweeping Day related to?

It has something to do with direct deduction.

According to legend, during the Spring and Autumn Period, Zhong Er, the son of the Jin Dynasty, went into exile to escape persecution. On the way to exile, he was tired and hungry in a deserted place and couldn't stand up anymore. I searched for it for a long time, but I couldn't find anything to eat. When everyone was in a hurry, I pushed the minister to a quiet place, cut a piece of meat from his thigh and cooked a bowl of broth for the son to drink. Zhong Er gradually recovered his spirit. Zhong Er shed tears when he found that the meat was cut off by mesons pushing his legs.

Nineteen years later, Zhong Er became the monarch, that is, the historical Jin Wengong. After he ascended the throne, Wen Gong rewarded the heroes who accompanied him in exile at first, but forgot to push the meson. Many people complained about meson push and advised him to admire it. However, mesons despise those who strive for merit the most. He packed his bags and quietly went to Mianshan to live in seclusion.

Hearing this, Jin Wengong was ashamed and personally took someone to ask Jiexiu, but Jiexiu had left home for Mianshan. Mianshan Mountain is high and dangerous, with dense trees. It's hard to find two people. Someone offered a plan to burn Mianshan from three sides and force a meson to push out. The fire burned all over Mianshan, but there was no trace of meson push. After the fire was put out, it was found that Jiezitui had sat under an old willow tree with his old mother on his back and died. Jin Wengong cried. When I was buried, I found a bloody book in a tree hole, which said, "May my master be clear forever." To commemorate meson tui, Jin Wengong ordered that this day be designated as Cold Food Festival.

The following year, Jin Wengong led the minister to climb a mountain to pay homage, and found that the old willow tree came back from the dead. He named the old willow "Qingming Willow" and told the world that the day after the Cold Food Festival was designated as Tomb-Sweeping Day.

Tomb-Sweeping Day, also known as the Walking Festival, is at the turn of mid-spring and late spring, that is, the first 108 day from winter to the future. It is a traditional festival in China, and it is also one of the most important festivals to worship ancestors and sweep graves. The traditional Tomb-Sweeping Day of the Han nationality in China began in the Zhou Dynasty and has a history of more than 2,500 years. Influenced by the Han culture, 24 ethnic minorities in China, such as Manchu, Hezhe, Zhuang, Oroqen, Dong, Tujia, Miao, Yao, Li, Shui, Jing and Qiang, also have the customs of Tomb-Sweeping Day. Grave sweeping, ancestor worship and outing are the basic themes.
