According to Ci Yuan: "Pakistan, an ancient country, is located in Chongqing, Hubei, Sichuan and Guizhou".

BC 1 1 century, participated in the attack of Zhou Wuwang. Because of their bravery and good fighting skills, the Pakistanis forced Zhou Wang's army to defect, and finally defeated Shang Zhouwang and established the Western Zhou Dynasty.

In the early years of the Western Zhou Dynasty, 7 1 vassal states split. Bashi was established as a enfeoffment country, and the leaders were the Zhou royal family and the viscount, so it was called Bazi country, usually referred to as Bazi country for short. Ba's area is roughly in the whole territory of Chongqing, from the upper reaches of Hanshui River in southern Shaanxi to the northern edge of Daba Mountain and Xiangyang in the east, and it began to expand in the Spring and Autumn Period. In the early Warring States period, under the influence of Chu, Pakistan moved southward to the mainstream of the Yangtze River, and successively established its capital between Qingjiang and Chongqing.
