Zhuanxu

Zhuanxu, grandson of Huangdi (Yellow Emperor) and son of Changyi, styled himself Gaoyang-shi and ranked among the Five Emperors as the primordial sovereign embodying the Virtue of Water in the northern realm. He ascended the throne at age twenty and established his capital at Diqiu. His greatest contribution was the ‘Separation of Heaven and Earth’ (Jue Di Tian Tong): in antiquity, humans and deities intermingled freely—every household conducted sacrifices and every individual claimed communion with spirits, resulting in widespread chaos. Zhuanxu appointed Chong and Li to assume distinct responsibilities for Heaven and Earth, severing unauthorized human access to the celestial realm and centralising ritual authority under designated priests—thus restoring clarity between sacred and profane, and establishing orderly relations between heaven and humanity. This reform marked a pivotal transformation in early Chinese religious and ritual institutions. He also observed the sun, moon, and stars to formulate a precise four-season calendar, guiding agricultural activities with the principle: ‘Observing the celestial bodies—the sun, moon, and stars—to reverently assign seasons and time to the people.’ Legend holds that after his death, he ascended on a dragon to the north, becoming the Black Emperor (Heidi), sovereign of the northern quarter, with Xuanwu as his divine attendant. For over a millennium, the Er Di Ling in Neihuang has maintained uninterrupted incense offerings in veneration of this sovereign of cosmic order.
