Shanxi Province, the capital of Taiyuan, is named after its location in the west of Taihang Mountain. Referred to as "gold", also known as "three gold". Shanxi is adjacent to Taihang Mountain in the east, Luliang Mountain and Yellow River in the west and south, and the Great Wall in the north. Bordering Hebei, Henan, Shaanxi, Inner Mongolia and other provinces, Liu Zongyuan called it "the mountains and rivers outside". Shanxi has a profound historical and cultural background, with a written history of 3,000 years, and is known as the cradle of Chinese civilization. As we all know, Hebei Province is called the land of Zhao Yan, Shandong Province is called the land of Qilu, Shaanxi Province is called the land of Sanqin, and Hunan Province is called the land of Sanxiang. Then, the question is, why is Shanxi Province called "Sanjin" or "the land of Sanjin"?

First of all, Shanxi is referred to as "Jin", also known as "Sanjin". The "Jin" here mainly refers to the Jin State of the Zhou Dynasty. Jin was a vassal state of the Zhou Dynasty. At the beginning of the Zhou Dynasty, Jin was named Hou by Zhou Tianzi. Her last name is Kim. As the most powerful vassal state in the Spring and Autumn Period, the territory of Jin covers the whole of Shanxi Province, eastern and northern Shaanxi Province, south-central Hebei Province, western and northern Henan Province, northwestern Shandong Province and Inner Mongolia in its heyday. So in the Spring and Autumn Period, today's Shanxi Province basically belongs to the State of Jin. Moreover, the capital cities of Quwo, Jinyang, Xinjiang and Xinjiang in the State of Jin are basically in today's Shanxi Province.

As for the capital of Jin, Quwo is mainly located in Quwo County, Linfen City, Shanxi Province, and Jinyang is located in Taiyuan City, Shanxi Province. So Jin is in Shanxi, just as Qin is in Shaanxi and Qilu is in Shandong. The appellation of "Sanjin" or "the land of Sanjin" is directly related to the historical event of "Sanjin divided and ruled". According to historical records such as Historical Records and Warring States Policy, a fierce struggle was waged among Fan, BOC, Zhi, Han, Zhao and Wei. Now, Fan and China Bank have been defeated first. In 453 BC, the Han, Zhao and Wei clans lost their branches, and the State of Jin was divided among them. In 403 BC, Zhou Weilie made Han, Zhao and Wei princes, which was called "the three tribes divided into Jin" in history. The three vassal States of Wei, Han and Zhao are collectively called "Three Jin" because they came from Jin.

After the three tribes were divided into Jin, the territory of Wei, Han and Zhao included parts of Shanxi Province today. More crucially, the three vassal states of Wei, Zhao and Han were once in today's Shanxi Province. Specifically, as far as South Korea is concerned, during the Spring and Autumn Period, the ancestor of the Korean monarch was once a doctor of the State of Jin and was sealed in Hanyuan. At the end of the Spring and Autumn Period, Han Zhenzi moved to Pingyang. During the Warring States Period, Pingyang became the first capital of South Korea. Pingyang corresponds to Linfen City, Shanxi Province today; As far as Zhao is concerned, the capital of Zhao was originally in Jinyang, and later moved to Handan, which is now Handan City, Hebei Province. The three clans were divided into the battle of Jinyang before the Jin Dynasty, and Zhao Xiangzi defeated his division in Jinyang, thus being divided into Jin with Wei Han.

Finally, Wei was one of the Seven Heroes of the Warring States Period. There are two capitals in history. As early as when Wei Zhaohan was divided into Jin, Wei was in Hedong, which is the southwest of Shanxi today, with Anyi as its capital, and its economic foundation was better than that of South Korea and Zhao. Anyi is mainly located in Xia County, Yuncheng City, Shanxi Province. For Anyi, it is located at the southwest end of Shanxi Province, at the junction of North China, Northwest China and Central Plains, at the west foot of Zhongtiao Mountain, at Pinglu County in the south, at wenxi county and Yuanqu County in the north, at Salt Lake District in the west, and across the Yellow River from Mianchi County in Henan Province in the east. So obviously, Wei, Zhao and Han, the seven heroes of the Warring States, finally moved their capitals to other places. However, at the end of the Spring and Autumn Period,
