Why do everyone say that "Jincheng" in Shanxi has a longer history than "Luoyang"?

Jincheng is one of the birthplaces of Chinese culture. Twenty thousand years ago, human ruins such as the Gaodu ruins, Tashui River, and Xiachuan were left. During the Tao and Tang Dynasties, Yao divided the world into nine states, and the entire territory of Jincheng belonged to Jizhou, and Ji Nei was the imperial capital. During the period of Yu and Shun, Shun divided the world into twelve states, which belonged to Jizhou. "Mozi" records: Shun cultivated Lishan (Qinshui) and fished in the lake (today's Yangcheng). During the Xia Dynasty, the twelve states were combined into Jiuzhou, which belonged to Jizhou.

"Warring States Policy" records: Tang attacked Jie in late summer, and Jie moved his capital from Anyi to Chui (today's urban area and suburbs). During the Shang Dynasty, it belonged to the hinterland of Jizhou Prefecture, with Shang Gai Kingdom (today's Gaoping territory) within its territory. "Lu's Spring and Autumn Annals" contains: Shangtang mulberry forest prepares for rain, and when it rains, it is the joy of the mulberry forest.
