20 12 several dragons control the water, several cows plow the fields, and several people divide the bread.

According to Mr. Wang, from the first day of the first month to the twelfth day of the first month, which day is the Dragon Day (that is, the morning day) or the Dragon Water Control Day, and which day is the Cow Day (that is, the ugly day) or Niu Geng, so there are only ten people sharing cakes at most, because there are only ten C's, the fourth day of this year is the Japanese, the seventh day is the ugly day, and the tenth day is the Renchen day. So this year is: ten dragons control the water, seven cows plow the fields, and four people share the cake. This is all superstition.
