Why is Beijing called Yan in ancient times, Shanxi called Jin in ancient times and Shandong called Qilu land in ancient times?

Yan Dou was named after the capital of ancient Yan State. Among the Seven Heroes in the Warring States Period, Yan was named after its proximity to the Yanshan Mountains. Later, it was often used as another name for Beijing in some ancient books.

According to historical records, after defeating Shang Dynasty in BC 1 1 century, the descendants of Emperor Yao were named Ji and Yan. Another way of saying it is that Zhou was once the state of Yan and Ji was the capital of this country, which is now the predecessor of Beijing. After Qin destroyed Yan State, Jixian County was established, which is located in present-day Beijing.

Shanxi was called Jin in the Spring and Autumn Period and the Warring States Period, called Jin in the Qin Dynasty, Bing and Hanoi after the Han Dynasty, and Taiyuan House in the Tang Dynasty.

In the early Western Zhou Dynasty, vassal states were enfeoffed on a large scale. South-central Shanxi is the territory of more than ten vassal states, and Jin is the main vassal state. During the Spring and Autumn Period, the State of Jin gradually grew, annexing small countries around it, forming a five-hegemony situation. The territory of the heyday of Jin State included most of Shanxi today, which is the origin of Shanxi abbreviation today.

Shandong was the land of Qilu in ancient times, so it was called Qilu. ? Qilu? This name was formed before Lu. By the end of the Warring States period, with the basic completion of national integration and humanistic assimilation, Qilu culture was gradually integrated. Due to cultural integration, Qilu? Formed a unified cultural circle, and? Qilu? Regional form is formed by a unified cultural circle. The area of this area is roughly the same as that of Shandong province, so it has become synonymous with Shandong.

Qilu? And then what? Shandong? Are geographical terms formed in history. The geographical scope they refer to seems to be exactly the same and can be used universally. But in history, the two are completely different. ? Shandong? Great changes have taken place in history. During the Song and Yuan Dynasties, today's Shandong area was only introduced as an administrative division, and its scope is still different from today's Shandong. It was not until the Qing Dynasty that it was officially named Shandong Province. After that, the scope of the area may change, but the name remains the same and the scope is not much different.

The predecessor of China City is different from its present name, but it is closely related.

From the ancient city names, we can see the modern evolution process. Maybe these place names will change with the development of the times in the future.
