The misty rain in the south of the Yangtze River wetted young Hou Xin's dream of hundreds of flowers, but it could not extinguish the light in his eyes. His mother died at the age of seven, his family was ruined at the age of twelve, and he was reduced from the son of a salt merchant to a handyman in the Su family. Fate gave him the most miserable start. But he had to blossom in a desperate situation - relying on his gift of photographic memory to learn secretly and become a talent, he met Su Yi, the daughter of the Taifu with a keen eye for pearls, and met Lu Helin, the queen of the generals who depended on each other for life and death. After entering the imperial examination and becoming an official, he experienced ups and downs in the officialdom and bloody border battles. He gradually climbed to the top of power and became an iron-blooded prime minister determined to reform. But in the dream, the flowers were blooming, but when I woke up, they were not there: the new policy angered the powerful and eventually led to defeat, the one I loved was forced to enter the palace as a concubine, and brothers who lived and died died on the battlefield. He gave a thousand kinds of love in exchange for a thousand kinds of hatred.
However, the story does not end in tragedy. After resigning and going into seclusion and writing books, Hou Xin completed his spiritual nirvana in the Jiangnan Thatched Cottage. His adopted son A Qi inherited his legacy and reformed the New Deal. His beloved Su Yi became a monk and started women's education. The deeds of his brothers Lu Helin became a legend in the border area. Three hundred years later, white cranes circled the temple, five hundred years later, the blood manuscript sank into the river and was recovered, and a thousand years later, wisteria flowers blossomed like snow. When archaeologists opened the jade box in his tomb, the "Letter to Those Who Come Later" revealed the truth: all personal love, hatred, gains and losses, honors and disgrace, have turned into the spring breeze of civilization and progress in the long river of time. This is an eternal story that begins with the disillusionment of "the flowers are blooming in the dream" and ends with "blood and tears turning into the spring breeze". It tells how idealists use the regrets of their lives to water the flowers of the spirit that will last for thousands of years.
