This book is written along the historical context, aiming to explore stories in history from a current perspective, bring down those lofty figures in history, turn sacred history into mortals, and try to describe the "real" history in the author's eyes with a humorous tone and a proud attitude. Don't travel through time, don't be arrogant. After all, most of us are mortals. The things of mortals are to eat, drink, poop, and sleep. The things of mortals are always immersed in the fact that they are the protagonists of the world, but they are always severely hit and crushed by reality. They have to feed themselves chicken soup to tell themselves to be strong, have to live humbly, and have to live happily.
