Overview.
The Confucian book, the Rites of Zhou, discusses the concept of the so-called "Wufang Shangdi". The Records of the Grand Historian, refers to the following: Cangdi (or "Qingdi"), Huangdi, Heidi, Chidi, and Baidi.
Dongyue Dadi.
Cangdi is known as Dongyue Dadi or the "Great Deity of the Eastern Peak" which refers to Mount Tai, a sacred mountain in China. 
He is worshipped in both Daoism and Chinese Buddhism with this name.
Long ago, people believed that Mount Tai was a place where spirits of the dead gathered. They thought that the god of Mount Tai was the most powerful god of the underworld and controlled people's lives and status on Earth. In Daoism, people say that Dōngyuèdàdì is the grandson of the Jade Emperor.
During the Han dynasty, the Feng Shan ceremony was held on Mount Tai. This was a very important ceremony, and the emperor had to complete it to show that he had the mandate of heaven. The ceremony began in 219 BC, during the reign of Qin Shi Huang, who was the first emperor of China.
Over time, the role of the Dongyue Emperor grew. He became more than a God of the local area. He became a god of life and death in general. In Taiwan, people perform a ritual called the storming of the city (打城) to honor the Dongyue Emperor. This shows how his role has changed over time.
