What is the historical origin of the calendar in western Guangdong?

As for the formation of the annual records, there is really not much information that can be found. We can only get some clues by adding inferences from the existing information. There are only three possibilities: 1. The ancestors of western Guangdong came from Brought over from the Central Plains 2. A festival held by the aboriginal people of western Guangdong in ancient times, which was absorbed by the ancestors who later migrated to Guangdong 3. A festival developed after the ancestors of western Guangdong moved and settled there.

Let’s look at the first possibility first. If the ancestors brought it from the Central Plains, then there should be annual customs, or shadows, in other parts of China. But needless to say in other places, even Putian and Ji'an, which have the closest blood relationship, can't find any trace of the year. So the first possibility is ruled out. The second possibility is the festival of the aboriginal people in western Guangdong. We can overturn it by following the clues of the aboriginal people. The aboriginal people in western Guangdong are the Li people. Since the ancestors of the Central Plains entered Guangdong, the Li people entered Hainan or Guangxi and became local ethnic minorities or more. Distant Vietnam, but no trace of year records can be found in Hainan, Guangxi or Vietnam, so the second possibility is ruled out. There is only the third possibility. It is a festival developed after the ancestors entered Guangdong, so it can form a strong local color.
