Huang San, referring to Emperor, Rehmannia glutinosa and Ren Huang, is the legendary three ancient emperors.
Emperor, originally refers to the supreme master of all things in the universe, that is, the God of Heaven.
Later, many countries fought for the title of emperor, and there appeared the Western Emperor, the Eastern Emperor, the Middle Emperor and the Northern Emperor.
Emperor, the Lord of creatures and the Sect of benefits, "is called emperor because of his prolificacy."
"The emperor is up, the emperor is down".
The "emperor" mentioned by the ancients refers to heaven and earth, while the word "emperor" tells people that heaven and earth are the masters of all things.
The ancient Three Emperors and Five Emperors, such as Huang Xi Fuxi, Uwahuang, Huangdi Xuanyuan and Yan Di Shennong, were not real emperors, but tribal leaders or tribal alliance leaders, and their "emperor" or "emperor" names were added by later generations.
Xia monarchs called it Hou, Shang monarchs called it Di, and Zhou called it Wang.
During the Warring States period, most governors arrogantly called themselves kings, honoring King Zhou as the "King of Heaven".
Ying Zheng, king of Qin, unified China, thinking that he "had both ability and political integrity and made contributions to the five emperors", and created the word "emperor" as the official title of the supreme ruler of China.
So Qin Shihuang Ying Zheng was the first emperor in China, calling himself "the first emperor".
From then on, "Emperor" replaced "Emperor" and "King" and became the title of the supreme ruler of feudal society in China for more than two thousand years.
