What is the tail bud in the solar term?

The entry of solar terms into the great cold means that the year of Gengzi in the front foot of the lunar calendar has essentially entered the "end". At this time, it is also the cold period after slight cold in most areas, because the atmospheric circulation affecting China is relatively stable, and the circulation adjustment period is about 20 days. In the process of atmospheric circulation adjustment, it will often bring large-scale wind cooling and rain and snow weather to China.

Laba is also called magic weapon festival, Buddha's enlightenment festival and enlightenment meeting. Originally a festival set up by Buddhism to commemorate the enlightenment of Sakyamuni Buddha, it gradually evolved into a traditional folk festival in China. It is a traditional custom for many local people to drink Laba porridge boiled with rice, millet, corn, coix seed, red dates, lotus seeds, peanuts, longan and various beans on Laba Festival.

As the saying goes, "Go to Laba in the cold and summer, and drink porridge to make tail teeth", what does it mean? What is a "tail tooth"?

In previous years, there was an important thing in the great cold solar terms, that is, to make "tail teeth", and the day of tail teeth was generally chosen on the sixteenth day of the twelfth lunar month. As the saying goes, "When the Great Cold arrives at Laba, you should drink porridge to make your tail teeth", which means that the Great Cold catches up with Laba Festival. After drinking Laba porridge, I will arrange to make my tail teeth in the next few days.

The so-called tooth-making was originally the custom of Minnan businessmen to offer sacrifices to their land fathers on the second and sixteenth day of the lunar calendar, which was also called "tooth-making" at that time. February 2 is the first time to make teeth, called "head teeth"; 1February 16 The dentist was the last dentist, also called "tail tooth". Later, it gradually evolved into a ceremony for merchants to thank their buddies and enhance their feelings. To put it bluntly, it's like a year-end thank-you banquet hosted by modern enterprises.
