The following is an answer.
During the nearly 300 years in the Spring and Autumn Period, the State of Chu successively destroyed and annexed 6 1. In Gao Shiqi's Zuo Zhuan Shi in the Qing Dynasty, it was said that "Mo Churuo was the person who destroyed the country the most in the Spring and Autumn Period". At its peak, Fiona Fang's territory reached 3,000 miles, including Hubei, Hunan, Jiangxi (except Xinjiang Valley), southern Henan, western Anhui, southeastern Shaanxi, northern Guangdong and northeastern Guangxi, spanning eight provinces, making it the largest southern country in the Spring and Autumn Period.

After entering the Warring States period, the development of Chu reached its peak. Relying on the reform of Wuqi, the king of Chu established a strong military and economic strength, launched an offensive against the surrounding areas, and constantly expanded his territory. In 334 BC, Chu Weiwang attacked the State of Yue and killed the King of Yue without borders. "I took Wu into Zhejiang and broke Xuzhou in the north. The more dispersed the clans are, the more they struggle for power and profit, or they claim to be kings, or they claim to be kings, standing on the sea in the south of the Yangtze River and serving the dynasty in Chu (Historical Records, Goujian Family of Yue King). As a result, the vast area of Yue, with Jiangsu and Zhejiang as the center, was incorporated into the territory of Chu.

In the mid-Warring States period, when the territory of Chu was the widest, it was bordered by the sea in the east, Bashu in the west, Guangdong and Guangxi in the south and southern Shaanxi in the north. It owns all or part of Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang, Henan, Shaanxi and Shandong, and its influence extends to Guizhou, Yunnan and Guangdong. The vast southern areas such as Jianghan Basin, Jianghuai Basin, Taihu Basin and Yuanxiang Basin have a land area of 6,543,800 square kilometers and a population of more than 5 million. Chu has millions of soldiers, which can store ten years' grain and stand tall in the east of the world!
