"The good things in the world are not strong, and the colorful clouds are easy to scatter and the glass is broken." Yesterday's prosperity has become desolate in the blink of an eye. In 975 AD, the Southern Tang Dynasty, which had been in existence for nearly 40 years, fell. In the past 40 years, the country, the country, and the mountains and rivers of three thousand miles were like a big dream. When this good dream was shattered, the past events disappeared one by one into the dust of history.
Concept: Life is like a dream, no one is a passer-by in history
