Both names are derived from Sanskrit, meaning turnover, change and transfer, which means that the sun runs around the zodiac and begins to transition to the New Year. The celebration lasts for three to seven days. The first day is called "Netmold" (meaning death). People think this day is unlucky, so they don't wash their hair, cut their hair or work. Let's catch the pendulum, race the dragon boat and raise the height. The next day it was called "net brain" (smelly meaning), which was considered unclean. You should take a bath, wash your hair, get a haircut, change clothes, wash Buddha statues and pagodas, hold performances at night, set off fireworks and lanterns, and send away all diseases, disasters, filth and cleanliness in one year to enter the new year. In the Dai calendar, these two days are considered as "empty days", not counting the old year or the new year. The third day is the first day of New Year's Day, which is called "overlord horse" (meaning God, also meaning the beginning of a year).
