There is a book called "Shang Shi Hua" that states that Luoyang was the capital when the Western Zhou Dynasty was first established. Is this really the case?

This is what it looks like. After the founding of the Western Zhou Dynasty, in order to control the immigrants from the Shang Dynasty, the Song Dynasty was established. At the same time, a city was built in Luoyi, and some immigrants from the Shang Dynasty were moved in. At the same time, troops were stationed near the city to play a role. The role of surveillance was the predecessor of Luoyang City, which was called Chengzhou at that time, and the original capital of the Zhou Dynasty was called Zongzhou. At that time, the king of the Western Zhou Dynasty still lived in Zongzhou.

In my opinion, this should be the earliest dual-capital system in Chinese history
