The general process is to “invite” the ancestors who passed away on New Year’s Eve, then offer dishes, candies, and fruits for worship, and on the second day of the lunar new year, visit the graves to “send off” the ancestors.
During the New Year period, it is customary to hang scrolls in the house, also called zhizi, which are family genealogy scrolls. The main part of the scrolls is written in a “tree diagram” format with the names of ancestors, and on both sides are couplets.
Honestly, based on my own experience, this feudal superstitious tradition maintained by clan law seems to have gradually faded away with the passing of the older generation under the deepening development of capitalism. Regions where capitalist production relations are not yet very developed still retain this relatively strong superstitious mindset. I think under the impact of capitalism, many small farmers have gone bankrupt and become the proletariat, leaving them no energy to engage in these practices, while those who have risen to become wealthy small bourgeois or capitalists often do not take ancestral blessings seriously, and even during the New Year, they are busy exploiting and do not return home.
