Zao Jun, also known as Tsao Shen or "kitchen spirits", are spirits whose nature encompasses metal and fire, and are associated with alchemy and homemaking. They are mostly small spirits, most often found in or near a kitchen in a single home, although they can also be found in conjunction with forges and alchemical laboratories.
They are among the most familiar spirits to most people, as they are among the most likely to interact with peasants on an individual or family basis. Given their association with a particular home, they are best placed to be favorably influenced by gifts or the payment of respect, and can develop longstanding relationships with a given family that last for many generations. A solid relationship with your family Zao Jun is considered to be very good luck, and can sometimes form the basis of a reputation for fair dealing that greater spirits and demons will pay heed to.
