After the fall of the Tang Dynasty, no one controlled China for 72 years.
The five northern dynasties took turns taking over the throne. The average emperor's term was four years, and the mortality rate was higher than that of a war correspondent. Ten small countries in the south lie down to eat melons and watch a show across the river. It can be called the largest double act in history.
Then Zhao Kuangyin came, bringing a glass of wine and a face, ending the farce.
This book is about the Song Dynasty, but the story of the Song Dynasty must start from this chaos. After all, if you don't know how crazy the front is, you won't understand why the back is so stable.
