The "Four Heavenly Kings" were originally the general names of the four dharma gods in Buddhism, commonly known as the "Four donkey kong". They are kings who dominate the country in the East, kings who grow up in the South, kings who have broad horizons in the West, and kings who are knowledgeable in the North. King Tota is one of the four great kings of Indian Buddhism. After it was introduced to China, influenced by China's culture and aesthetic consciousness, it showed remarkable cultural characteristics in China: wearing armor, wearing a golden wing and a black crown, holding the tower in the left hand and the tower in the right hand. Therefore, the North King of Heaven is the predecessor of "King Tota Li Tian". In Journey to the West, Wen Tianwang and Li Tianwang were separated, but obviously Li Tianwang was in the Crown Vocational College.
