Chinese ancestor worship, or Chinese ancestor veneration, also called the Chinese patriarchal religion, is an aspect of the Chinese traditional religion which revolves around the ritual celebration of the deified ancestors and tutelary deities of people with the same surname organised into lineage societies in ancestral shrines. Ancestors, their ghosts, or spirits, and gods are considered part of “this world,” that is, they are neither supernatural (in the sense of being outside nature) nor transcendent in the sense of being beyond nature. The ancestors are humans who have become godly beings, beings who keep their individual identities. For this reason, Chinese religion is founded on veneration of ancestors. Ancestors are believed to be a means of connection to the supreme power of Tian (Shangdi), as they are considered embodiments or reproducers of the creative order of Heaven.
