In the autumn of the seventeenth year of the Yuan Dynasty, the wind in Dadu was like crazy, roaring with yellow sand all over the sky, like countless tiny sand blades, which made people's cheeks hurt. It also whizzed past the majestic glazed tiles of the palace wall, grinding away the remaining majesty of the royal family. The yellow sand was covered with dust and rushed all the way into the narrow alleys in the south of the city, passing over the mottled brick walls, and landed on the inconspicuous "Yanxin Teahouse", a short house with green tiles. The green tiles of the teahouse were covered with a thin layer of dust and frost, blending in with the surrounding dilapidated streets. It was inconspicuous, but it hid unknown secrets.
