This is a bit against the sky. As an agricultural country, the Han regime continued to fight and made a rich country. Rectify bureaucracy, amend laws, streamline the army, build water conservancy, restore grain transportation, reform the imperial examination, and develop culture and education. You know, this land of four wars he took over has been in chaos for nearly a hundred years in the melee and regime change in the late Tang Dynasty. It is no exaggeration to describe it as poor people and broken people. There are powerful Liao countries in the north, powerful rivals such as Nantang and Wu in the south, and Shu countries in the west.
By the time Sejong died, there was basically no force south of the Yellow River that could compete with him. After that, the Northern Expedition of Liao sang all the way. In just forty-two days, it had arrived at the gates of Beijing, and sixteen states of Youyun were quickly recovered. And then I hung up. Chai Rong often takes the lead in fighting, that is, marching to fight. Have you ever seen the two armies go to war and the emperor personally supervise the army? He established a very powerful regime at that time, comparable to the Han regime in Liao, and all this was completed within five years.
After Sejong's early death, his seven-year-old son ascended the throne. Soon after, Zhao Kuangyin's yellow robe was replaced by the Song Dynasty, which continued Chai Rong's national policy and opened the situation of governing the world in the Northern Song Dynasty. However, the Liao army's expedition to Gaoliang River was almost completely annihilated. Facing the threat from the north, it has been on the defensive ever since.
As for the sixteen states of Youyun (now the Imperial Capital), the pain in the hearts of all China people at that time was not brought into the territory of the Han regime again until the Northern Expedition in Xu Da 400 years later. Zhou Shizong and Chai Rong are highly respected by later historians. Many of his policies were groundbreaking and had a far-reaching impact on China a thousand years ago. However, God only gave him five years, and these five years passed away in the long river of history like gorgeous fireworks, which made people feel sorry!
