This historical knowledge is clearly stated in junior high school textbooks.
Everyone knows that "the five tyrants in the Spring and Autumn Period and the seven heroes in the Warring States Period".
From the ancient map, the "Seven Heroes of the Warring States" are Qi, Chu, Qin, Yan, Zhao, Wei and Han. Division is different from modern maps. Compared with today's map, the territory of each country is staggered.
Qi: In today's Shandong. It occupies part of the territory of southwest Hebei and southeast Shanxi. The capital is now Zibo.
Chu: In today's Hubei. Occupy parts of Henan, Anhui and Hunan. The capital is now Hubei.
Guo Qin: In Shaanxi today. Occupy part of the territory of Gansu and Sichuan. The capital is now Xianyang, Shaanxi.
Guo Yan: In today's Hebei Province. Occupy part of the territory of the three northeastern provinces. The present capital is Beijing. So Beijing is also called Yanjing.
Zhao Guo: In today's Hebei. It occupied part of the territory of Shanxi and Inner Mongolia today. The capital is now Handan City, Hebei Province.
Guo Wei: In today's Henan, it occupies most of the territory of Shaanxi today. The capital is in Kaifeng, Henan Province today.
North Korea: In today's Henan. Occupy most of Shanxi's territory. The capital is now Xinzheng, Henan.
This is the territory of seven men who occupy this country. Welcome to discuss each other.
Qin state
First of all, as far as Qin State is concerned, during the Warring States period, the territory of various countries often changed because of frequent merger wars. In the early Warring States period, Qin mainly occupied Gansu and Shaanxi provinces today. Later, under the conquest of Bai Qi, Sima Cuo and others, today's Sichuan, Chongqing, Shanxi, Henan and other parts were also included in the territory of Qin. Of course, when Qin Shihuang unified the territory of China, I won't list it.
the Kingdom of Wei（220-265 A.D）
After the division of Sanjin, Wei got the most fertile land, occupied some areas such as Shanxi, Henan and Hebei today, and lived in the land of the four wars during the Warring States period.
South Korea
For Wei, Zhao and Han, South Korea's national strength is the weakest. After the demise of Zheng, the main ruling areas of South Korea were concentrated in today's Henan area.

Zhao, also from the State of Jin, initially ruled mainly in today's Hebei and Shanxi regions. After King Wuling of Zhao rode and shot at Khufu, the State of Zhao destroyed Zhongshan and actively expanded outward. As a result, Zhao's ruling area also reached today's Inner Mongolia, Shaanxi and other regions.

In the history of the Warring States, the land area of Chu was once the largest, accounting for almost half of the world at that time. After the State of Chu annexed Lu and Yue successively, it extended its ruling area to the Central Plains such as Shandong in addition to southern identities such as Hubei, Hubei, Guizhou, Jiangxi, Anhui, Jiangsu and Zhejiang.
Qi state
In the ancient history of China, Shandong was called the land of Qilu, most of which was occupied by Qi. Of course, in addition to Shandong, Qi's power also extends to surrounding areas such as Henan and Hebei.

In the ancient history of China, Beijing was also called Yanjing, which was closely related to the Yan State during the Spring and Autumn Period and the Warring States Period. In addition to Beijing, Tianjin, Hebei and other places, Yan also actively expanded to today's Liaoning area.
