1. Measure the height of the ground around the yard and determine the height of the north side and the south side of the fence, so that the fence will be higher in the north and lower in the south with the fluctuation of the ground. At the same time, the slope of the wall should be determined, so that the water intake of the wall faces south and the rainwater can be effectively discharged.

2. Choose durable materials. Common materials are stone, adobe and bamboo. While selecting materials, we should also consider the design structure, such as leaving appropriate gaps on the wall to facilitate ventilation and drainage and reduce the weight of the wall.

3. Pay attention to the flatness, verticality and stability of the wall, as well as the climatic adaptability and structural stability of the selected materials during construction. After the wall construction is completed, it needs regular maintenance and inspection to ensure the service life and stability of the wall.
