Prime Minister of Chang'an

Chang'an in the Han and Tang Dynasties was surrounded by eight rivers. Wei, Jing, Feng, Lao, Lao, Pou, Chan and Ba have nourished Guanzhong for thousands of years, and also nurtured an imperial capital that is famous all over the world. But prosperity eventually comes to an end. War, siltation, diversion and erosion over time have gradually silenced the water veins that once ran beneath the city. Chang'an lost its water and gradually lost the old atmosphere of the prosperous Han and Tang Dynasties. But no one knows that underground in this ancient city, a set of culvert water systems that began in the Sui and Tang Dynasties and have been repaired through several dynasties has never really disappeared. One generation searches, one generation mends, one generation keeps secrets. Until Lu Xingzhi, who was eighteen years old, set up a calligraphy booth at the base of the city wall. He originally just wanted to make a living by relying on the forty-nine yuan code left by his father, but by chance, he got a copper beast buried underground. Subsequently, old houses, land deeds, counterfeit money, disappearances, chambers of commerce, and seemingly unrelated small things in the market began to point to the same secret. The half-volume fragment of pictures left behind by my father finally showed its true appearance. Eighteen gates affect eight waters. Some people spend their whole lives looking for it, some want to use it to rebuild Chang'an, and some people have been silent for eighteen years in order to protect it. When the clues left by generations of people finally merged into a complete water vein map, Lu Xingzhi realized that what he was tracing was never just an underground channel. It is about the rise and fall of a city, the obsession of a group of people, and the last choice left to him by his father. The locust flowers fall and the situation rises. The water is still and the situation is deep. Peace of mind, peace of mind.
