Sao Fah Din, or the ‘Pillar of Heaven and Earth’, is a freestanding wooden spirit post typically found in open-air settings, especially at Chinese shrines, where it is typically adorned with dragons coiling around it. The pillar symbolizes the connection between heaven and earth, represents divine protection, and is believed to be the place where the Jade Emperor, the supreme ruler of all gods in Chinese mythology, delivers royal commands from heaven to the human world.
