Ancestor veneration in China
Chinese ancestor veneration, also called Chinese ancestor worship, 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".
