Any powerful empire has its weaknesses. The so-called buildings will collapse and heroes will be late, so history always makes people feel sad.The Han Empire run by Liu's royal family established the dignity and confidence of a nation, but was finally killed by the treacherous history. When it comes to Chinese civilization, it is ten thousand years old.What is still fascinating and often amazing is the Han Dynasty.From Liu Bang's accession to the throne in 202 BC to the abolition of Emperor Xian of the Han Dynasty in 220 AD, the Han Dynasty ruled China for more than 400 years, except for Wang Mang's short-term usurpation of power. Countless fierce battles with the Xiongnu and other ethnic groups finally established the central position of the Chinese nation in the East Asian continent in the future.

At this time, the Chinese nation had experienced the Axial Age of vigorous vitality and creativity, and began to enter a period of comprehensive development and expansion.Just walked out of the ancient times when blood and fire swept away the wilderness.There is still a rough and savage aura left on his body.The contention of a hundred schools of thought in the Spring and Autumn and Warring States periods has accumulated the energy and wisdom to subvert the universe.Since then, the appearance of the land of China has undergone earth-shaking changes, and the pattern of Asia has taken on a new look, and the aftermath has spread all the way to the far western world.Just as Gao Zu sang in "Song of the Swan", "The swan flies high and flies thousands of miles with one stroke. The feathers and hives are already there, and they span the world."

Such a mighty Han suddenly stopped the beating of a mighty heart. The huge empire that collapsed suddenly, what inserted into its weakness?
