When is the twentieth day of the winter moon? Please kill the pig.

The 20th of winter is the day to kill pigs, so it's good to kill pigs. Killing pigs usually begins on the twentieth day of the lunar winter. At this time, people will make appointments with the pig butcher one after another. The pig butcher must take a notebook and write down the date from door to door, even to the morning and afternoon. Because at that time every family would kill pigs. Bring the fat pig that has been raised for a year to slaughter, and then invite all people, old and young, relatives and friends and neighbors to soak in the house and share the rich pork dinner and the joy of the upcoming Spring Festival. The master ate and went to the west, and the west ate and went to the master. When you meet a large group of people or a big village, it's almost time to celebrate the New Year.
