What is the population of Zou in China?

Zou has a population of 4.5 million, accounting for about 0.45% of the national population. Zou, one of the surnames in China, ranks 60th among surnames in China today, with many origins. One of them originated from Yao, whose surname is Zou: Yao in Shun Di. Shun is good at divination and prophecy, also known as Yao Shun. The descendants of Yao established Zou State, which was the earliest Zou State and the vassal state of Shang Dynasty. The name code "surname _" reads: "Zou Guo, Shun Hou, Yao surname". Originated from Cao surname, from Zou state, it was changed by Lu Mugong during the Warring States period, and it belongs to the country name. In the early years of the Western Zhou Dynasty, Cao Xie, a descendant of Zhuan Xu, one of the five emperors, was enfeoffed and established Zou Guo, also known as Zou Louguo. Originally established in Zou (now Qufu Village, Shandong Province), it moved to Iraq (now Jiwangcheng, Zou County, Shandong Province) in the middle of the Spring and Autumn Period. Zou Louguo was weak, and later became a vassal state of Lu, a big country, and was repeatedly oppressed and plundered by Lu. During the period from the seventh year of the reign of King Lie Zhou to the twenty-ninth year of the reign of King Wang (from 369 BC to 340 BC), Chu Xuanwang Xiong personally led the Chu army to destroy Zou, that is, Zou and Xiao Zou, and took away the subjects of Er Zou Guojun and escorted them to the southwest of Jingchu. After the state of Zou was annexed by Chu, the people of the old country took the original country name as their surname, called Zou, which was passed down from generation to generation, and was as famous as Liao and Zhu.
