Reunion and harvest have placed good wishes for the new year. According to Yunnan Literature Network, Yunnan pig-killing rice, also known as pig-killing year, is usually cooked in the winter and twelfth month of the lunar calendar every year, which is also the season for eating rice, and it can also be said that it is the happiest time before the Spring Festival. This is a local folk activity in Yunnan. When celebrating the New Year in December of the lunar calendar, every family gets together, kills a pig and invites relatives and friends to dinner.
