The Ox King Festival is a traditional festival for the Buyi, Miao and Gelao ethnic groups in Anshun.

Some Buyi people hold the festival on March 3 of the lunar calendar, while some on April 8 of the lunar calendar. They will kill pigs and dogs as sacrifice to the mountains, clean the village, eat five-colored sticky rice cake and Qingming cake, worship ancestors, and feed cattle with drink and food. The Miao people usually hold the festival sometime from April to June on the lunar calendar. For Gelao people, they are likely to hold the festival on October 1 of the lunar calendar.

During the Ox King Festival, which is said to be the ox king's birthday, every family shall prepare chicken and wine as well as glutinous rice cake to worship the ox king. They hang glutinous rice cake on ox horns, take good care of their cattle, and keep the cattle well fed.
