Ni (ní), whose surname comes from the fief of the late emperor Zhuan Xu, belongs to the national title. In ancient times, there lived a clan on today's Shandong Peninsula. They worship spiders for various inexplicable reasons, believing that all clan members are descendants of this sacred spider and are protected by it. Therefore, they regarded spiders as ancestors' sacrifices, totems and emblems of this clan, and called this clan "Zhu". The ancient Yi people mainly lived in Zouxian County, Shandong Province. They call their places of residence Zhucheng (now Zouxian County, Shandong Province) and Zhuchan (also known as Zoushan and Zhuchan, which are located at the south of Zouxian County 16 km) and so on. During the reign of Ji Fa, Cao An (the fifth son of Lv Zhong), the descendant of Zhuan Xu Emperor, was appointed as a vassal, and later became a vassal (now Feixian, Zouxian, tengxian, Jining and Jinxiang, etc.). ), established the state of Zhu. Guo was weak and attached to the Zhou Dynasty, and later to the powerful Lu State. Guo's name was also written as "Lou" in the classics, and was also commonly known as "Zou" or "Li" in the Warring States period. After textual research by experts and scholars, it is considered that "Luan Lou" is a local dialect and "Luan" is a proper name, while Zou and Li are homophones used after the Warring States Period, which are the same as Yan in Yan State. The country established by has undergone great changes and development, and Xiao Zhu and Guo Guo have appeared. Because of his pioneering work, he was also respected by later generations as the great ancestor of Zhu, Yun, Yan, Zou and Lou. There was a famous minister of the Western Han Dynasty, Ni Kuan, a hydraulic scientist. He is a native of Qiancheng County (now gaoqing county, Shandong Province), specializing in history. He worked as an imperial adviser and a left-handed civil servant, and later worshipped the imperial adviser. During his tenure, Ni Kuan attached great importance to water conservancy construction, dispatched migrant workers, and opened six auxiliary canals on the south bank of Zheng Guoqu to irrigate the surrounding highlands. He made outstanding achievements and won the praise of the court and the support of the people. There are always different opinions about who the Ni family started from, but its descendant Ni Kuan is quite famous in the history books, so most members of the Ni family in later generations respect Ni Kuan as their ancestor.

Therefore, Cao Shi, Ni surname and Zhu surname are actually of the same clan, and the combined population of these three surnames has exceeded 30 million, ahead of Zhao, who ranked eighth in the 20th century. Originated from Xianbei people, since the Northern and Southern Dynasties, Xianbei, a shepherd boy, belongs to the Han culture and changed his surname to Shi. According to Records of Historical Records of Shu Wei, after Wei Dynasty, He Yong's compound surname was changed to Tan, and then to Ni.

He Yong's ancestor was a Tugu Hunbu of Murong Xianbei, which was changed to a single surname of Chinese characters when Emperor Xiaowen of the Northern Wei Dynasty carried out the policy of sinicization. Some people call it why, others call it Tan. Later, with the historical process of integration into the Han nationality, it was renamed Ni, and the number was far greater than that of the descendants of Yan Hou, which was passed down from generation to generation. Originated from Mongolians, it came from Manai Town of Mongolians in Yuan Dynasty, and it was a Chinese name change. According to the historical records "Tongzhi of Qing Dynasty, A Brief History of Clans and Manchu Eight Banners Surnames", the Mongolian Nimacha people, also known as Nimacha people and Zhunmacha people, originated in the Naima town of Mongolia in the Yuan Dynasty. Their ancestors were the forehead and the army, taking their surname as their surname, and then lived in Nimacha (now Ussurisk, Russia, the other side of the lake in Muling Dongxing, Heilongjiang) and Suiye (now Uzbekistan). If Manchu people were involved,

After the mid-Qing Dynasty, many Han surnames, such as Ni, Yang, Yu, Zhang, Jia, Ni, Yu, He and Zhang, appeared in Nimacha of Mongolian and Manchu. Originated from Manchu, from the Nuzhen Sanbu in the Jin Dynasty, it belongs to the sinicization and surname change. According to the Qing dynasty annals, imperial clan policy, Manchu Eight Banners surname records:

The Nisha ethnic group of Manchu, also known as Nisha ethnic group and Nisha ethnic group, originated from the Jurchen ethnic group in the Jin Dynasty, taking the surname as the surname, and Nishahala in Manchu, which means "solid" in Chinese, and lived in Nandulu (now the coastal area of Russia), Nisha (now the area below Longtan Mountain in Jilin), Suifenhe River in Wusuli (now the upper reaches of Suifenhe River) and other places. Originated from other ethnic minorities, it belongs to Chinese culture and changed its surname to surname.

Today, among Tujia, Miao, Dong and other ethnic minorities, there are Ni clan people. Their origins were mostly changed to the Han Ni clan in the policy of imprisonment and the movement of changing the land to the stream promoted by the central government during the Tang, Song, Yuan, Ming and Qing Dynasties, which was passed down from generation to generation.
