The dynasties with cities in Shaanxi Province as their capitals include the Western Zhou, Qin, Western Han, Sui, and Tang dynasties,
The dynasties with cities in Henan Province as their capitals include the Xia and Shang dynasties, the Eastern Zhou Dynasty, the Eastern Han Dynasty, the Cao Wei Dynasty, the Western Jin Dynasty, the Northern Wei Dynasty, the Song Dynasty, and the Later Tang Dynasty,
They are very important as important nuclei of the continent, and are equally important in their own right!
Overall, Henan has been the capital city for a longer time than Shaanxi. And after the Yuan and Song dynasties, China's economic center of gravity gradually shifted southward, while the center of gravity of governance gradually shifted to Beijing and Nanjing, and since then, Shaanxi and Henan have ceased to be the center of China.
So to speak, Henan is the cradle of civilization, Shaanxi is the pinnacle of civilization, and after the Song Dynasty, it gradually retired and became two in the square dance together, while the Yuan, Ming and Qing until today, Beijing and Nanjing, has always become the center.
