Changbussi, or Clown God, is a deity in charge of entertainment and the arts.
Alternate versions of the name include Changbu and Changbudaesin. It is believed that a famous clown died and was enshrined, or deified. Good fortune rituals (jaesugut) held in the Seoul and Gyeonggi regions include a segment dedicated to Changbussi, a character of artistic and theatrical spirit that requires a loud and entertaining performance by musicians and dancers. The deity is also responsible for protecting the people against calamities and bad fortune through the twelve months of the year. The Changbu Segment is generally performed as the eleventh of the twelve segments.
