Abstract: In prehistoric times, ancient humans began to live in Shanxi which was one of the birthplaces of Chinese civilization. Nearly 10000 years ago, Chinese ancestors started their farming practices here. They used stone tools such as stone axe, si, shovel and plough, and prepared soil for planting crops. Then, they used stone hoes to weed and loosen the soil to preserve soil moisture and finally used stone knifes and sickles to harvest crops. The author summed up and described the stone tools used in ancient Shanxi and pointed out that the farming methods and procedures at that time were rough and primitive but had opportunities to be improved and perfected with broad prospects as new-emerging things. The ancient ancestors at this phase took the first step toward food creation and consciously changed the ecological order of the field, demonstrated the influence of human action on the surface of the earth. The ancestors initiated the economic situation of primitive agriculture in a role of pioneer. These tools and methods laid a deep and solid foundation for later agricultural intensive and meticulous farming.
