In "White Deer Plain", Zhang Jia translated how to plow the land in the Guanzhong Plain.
In White Deer Plain, the scene of Zhang Jiayi plowing the land with a farmer's plow appeared in a certain chapter of the novel. According to the novel, the farm plow was a traditional farming tool. Its working principle was to use the plowshare to cut a groove on the surface of the soil and then pour fertilizer or a seeder into the groove for farming. When using a farmer's plow to plow the land, Zhang Jiayi had to first clean the plow and then soak it in warm water for about half an hour to remove the dirt and corrosion on the surface. Then he inserted the front part of the plow into the soil, stuck the handle out of the ground, and gently tapped the soil with the shovel to help the plow share go deep into the soil. After that, Zhang Jiayi inserted the back of the plow into the soil and adjusted the angle and strength of the plow to find the best depth and width of the cultivated land. Finally, he used the ploughshare to push the ploughshare into the soil to start farming. It should be noted that the farmer's plow was a traditional farming tool. Its usage methods and techniques were more complicated and required experienced farmers to master. In actual use, it was also necessary to pay attention to the depth and width of the cultivated land to avoid affecting the growth and yield of crops.
