The Yellow Emperor was born by the Ji River.
1, it is said that the Yellow Emperor was born by a river called "Ji", thus forming the surname of Ji. The nobles of the Zhou Dynasty were descendants of the Yellow Emperor, so Zhou Wenwang was also called Ji Chang. Zhou Wuwang is called Ji Fa. After the demise of the Zhou dynasty, the descendants of the Zhou royal family took the country name as their surname; During the reign of Emperor Xuanzong of the Tang Dynasty, in order to avoid the emperor's anonymity, he began to change his surname to Zhou. Later, someone restored Ji's surname, so Zhou and Ji's surname were kin.
There is discipline among the sons of the Yellow Emperor.
2. The Yellow Emperor has 25 sons, each with 12 surnames, including Ji. Later five emperors, Zhuan Xu, Yao, Shun, Yu, and the ancestors of Shang and Zhou were all descendants of the Yellow Emperor. These descendants inherited the surname Ji, and his descendants established the Zhou Dynasty. In the early years of the Western Zhou Dynasty, there were 53 governors named Ji. Most of the descendants of these countries with the surname of Ji changed their surnames to national surnames, feudal surnames, grandfather surnames and numbers, so there were not many surnames of Ji. In addition, in the Tang Dynasty, in order to avoid taboos, Ji's surname was changed to Zhou.
