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

Winter twentieth is the day to kill pigs, and killing pigs is very good. 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, and the pig butcher will 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. Take the pig that has been raised for a year to slaughter, and then invite all people, old and young, relatives and friends, and neighbors to have a lively dip at home to share the sumptuous pork dinner and the joy of the upcoming Chinese New Year. 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 the Spring Festival.
