Xiao Qingyun, a young man from a branch of the Xiao family in Lanling and a merchant family, followed his father to Chang'an to make a living. His family business collapsed overnight, he was enslaved and his pay was reduced, and he became a servant of the creditor Wang's family in the West City.
He climbed up from the mud: settling accounts, identifying goods, dealing with Hu merchants, starting from scratch, opening a silk and satin shop, and spreading the business route to the depths of the Silk Road. But because "people from industrial and commercial backgrounds should not predict what scholars should do", he read all the books of sages and could not even enter the examination room.
Until the night of Lantern Festival, a frightened horse crashed into the shadow of his lamp - it was Chen Wanxi, the tiger girl of Jiangmen. The family background is like a natural chasm, he hides and she chases; poems and letters fill up the worries of a scholar who cannot enter the examination room for half his life.
The prosperous age is about to fall, and the earth is coming with the encouragement of Yuyang and Chao. He spent half of his family fortune to save the Chen family from collapse and marry his sweetheart, but then he faced the destruction of the city, the death of his father, and the death of his best friend...
In troubled times, he had only one thought: to protect the flower he broke off.
