Late Song Dynasty: Saving Hundreds of Millions of Chinese People

Traveling through the Northern Song Dynasty, I met Li Qingzhao and took her to see all the flowers in Chang'an in one day. Look at Song Huizong and how Song Qinzong sought death, while Li Huaguang accumulated food, built high walls, slowly proclaimed himself king, and physically eliminated all unstable factors in the world. After a hundred or thousand years, there will only be civil strife and no more foreign invasion. If there are foreign enemies, they are only enemies from outside the world.
