What was the importance of the Yiluo River to Dugi in the late Xia period?

In ancient times, the Yi River and the Luo River intersected in the west of Yanshi, and even in the territory of the original Luoyang. It stretches from the western part of Henan Province and the southern part of Shanxi Province to the junction of Henan Province, Shandong Province and Hebei Province in the east, to the northern part of Hubei Province in the south, and to the southern part of Hebei Province in the north. The geographical center of this region is the area of Yanshi, Dengfeng, Xinmi and Yuzhou.

At that time, Xia's power extended to the north and south of the Yellow River, and even the Yangtze River basin. In the early Xia Dynasty, the Xia people mainly moved to the Hanoi area in the south-central part of Shanxi, moving to the southeast along the Fenshui and Heshui rivers, and in the late period, they reached the Yi and Luo River basins in central Henan. The "Chinese Zhou Yushang" says, "Xiyiluo exhausted and died in Xia", which shows the importance of Yiluo River water to Dugi in the late summer.

According to the local chronicles, the Yi River swelled several times, and after leaving the dragon gate, it rushed straight to the north, that is, outside the south pass of Luoyang, and merged with the Luo River to divert the Yi River. Rivers are important for the stability of the country. <>

It should be said that the scope of activity is not a direct ruling area, and the Xia people directly rule their own tribe and indirectly rule Kyushu, mainly to collect taxes.

It's not very big, it's primitive after all. And it's hard to calculate.

The Xia Dynasty was a period of transition from a city-state alliance to a feudal state, so there was no clear territory.

The core territory of the Xia Dynasty stretched from the western part of Henan Province and the southern part of Shanxi Province in the west, to the junction of Henan, Shandong and Anhui provinces in the east, to the northern part of Hubei Province in the south, and to the southern part of Hebei Province in the north. The geographical center of this region is the area of Yanshi, Dengfeng, Xinmi and Yuzhou.

There are many changes in the capital: Yangcheng (now Dengfeng Xucheng Town, Zhengzhou, Henan), Yangzhai (now Yuzhou, Xuchang, Henan), Zhucheng (now Yanshi Erlitou Ruins in Luoyang, Henan), Shangqiu (now Suiyang District, Shangqiu, Henan), Luncheng (now 35 miles southeast of Limin Town, Yucheng County, Shangqiu, Henan), etc.

The summer capital is in Xia County, Jinnan, Shanxi Province today. Of course, there is a lot of debate about it, because nothing concrete and substantial has been found now.

The territory of the Xia Dynasty stretched from the western part of Henan Province and the southern part of Shanxi Province in the west; east to the junction of Henan Province, Shandong Province and Hebei Province; It stretches from Hubei Province in the south to Hebei Province in the north. At that time, Xia's power extended to the north and south of the Yellow River, and even the Yangtze River basin. The Xia Dynasty built the capital Yangcheng (the eastern part of present-day Dengfeng, Henan Province), Xicheng (the northwest of present-day Dengfeng, Henan Province), and Anyi (the northwestern part of Xia County, Shanxi Province).

The place where the monarch lived was originally (northwest of present-day Jiyuan City, Henan).

The picture below is said to be a historical material that has no historical data to prove that it is really effective to hype. So we're not sure exactly how big it is. Then all we can learn or know is knowledge from books.

The knowledge points in the books are not necessarily correct. I guess I won't be able to find it until Monday.

The main area of Xia Dynasty activity was the middle and lower reaches of the Yellow River (equivalent to the present-day Shanxi, Henan, and Hebei regions), and the capital was built in Anyi.
