The origin of the Yi Year is about 30 words.

The Yi calendar year is a traditional festival of the Yi people, and the Yi language is called "Ku Zhi". It will be held in lunar calendar 10 and Gregorian calendar 1 10. In villages where the Yi people live in compact communities, auspicious days begin on June 10 of the lunar calendar and end on 30th. Due to the differences of auspicious days in different places, some Gregorian calendar days are early, some are in the middle and some are late. Every village has a three-day Yi calendar year. Therefore, it has a month's explanation in the Yi calendar year. The Yi calendar year has the meaning of celebrating that year, offering sacrifices to ancestors and praying for good weather, abundant crops, prosperous livestock and all the best in the coming year. Why does the Lunar New Year celebrate in October? Legend has it that there are two reasons. First of all, there are ten months in Yi history as a year. According to this calendar, October is the end and beginning of a year, which coincides with the New Year in China, so it is customarily called "October Year". Second, because during this period, the crops in the Yi area have been harvested, and the crops are abundant and slack, which is suitable for the New Year.
