February 2, why do you want to eat pig's head meat?

In ancient times, pig heads were used to worship ancestors and heaven.

Northerners cook pig's heads on February 2, when the dragon looks up, because the first and fifteenth days of the first lunar month have passed, and February 2 is the last festival of the Spring Festival. The average farmer worked hard for a year, killing pigs and sheep on the 23rd of the twelfth lunar month. After the first month, all the pork killed in the twelfth lunar month was basically eaten, and only one pig head was left to eat on February 2.

On February 2, the dragon raised its head, and everything on the earth began to revive, and all animals and plants began to raise their heads. We should make a good start in the new year and welcome good weather. The Dragon King is in charge of rainfall. When he goes to the Heavenly Palace, farmers will offer the best sacrifices to the Dragon King. It seems that the pig's head is a sacrifice to ancestors and heaven.
