Introduction to Gexi Mountain: On the north bank of Oujiang River, there is a stone road along the river from west to north, and I don’t know how many generations of people have walked there. The stones are so smooth that even if you walk barefoot, they feel extremely slippery. You don't have to worry about scratching the soles of your feet. Below the road are dams and rivers, and above are densely packed houses. Before it was submerged, it was the seat of the Dayuan Township government. The township health center is located at the upper reaches. It is a two-story brick and wood structure house, facing a corridor to the south. The upper and lower floors have the same structure. A wider patio is surrounded by a wall in front. There is a door connecting the east and west, and the wall next to the east gate A stove was built to burn the fire. To the left of the health center is the township government building. It is a two-story brick-concrete structure with the same structure upstairs and downstairs. There is a corridor to the south. Except for the larger conference room in the middle, the other single rooms are divided equally into two rooms, inside and outside. From the ferry head to the township government, there is a wide stone-stepped avenue. As you go up, there is a blacksmith shop. To the left of the shop is the fertilizer warehouse of the supply and marketing cooperative. The mixed smell of superphosphate, fertilizer powder and ammonia floats all day long. To the left of the fertilizer warehouse is a larger "cement flat" where villagers dry grain during the day and gather at night. The best house downstream is the forestry station. A large square square piece of land was built with stones and piled with wood, so that it became the only angular building in the entire river. Behind the village is a vast forest of Camellia oleifera trees. On frosty days in winter, hundreds of people who pick tea seeds and pick tea seeds go up the mountain together, so the wolf clothes under the trees are also stepped smooth. If you can't keep your mouth shut, the mountain will be filled with people.
