"Diligence" advocated by Jia Sixie is not only aimed at laborers, but also at all members of society, including rulers. In the preface, he cited examples such as "Shen Nong is haggard, Yao is thin, dark and redundant", and in "Comfort the people", he cited the hard work of Ren Yan, Wang Jing, Huang Huanglong, Ci Chong, Gong Sui, and came to the conclusion that although the land of fish and turtles is a "crop", it is a field for cultivating crops, and this gentleman is also careful. It was based on the title of squire that bittern was sown in Oracle bones, and Zheng Baicheng had no hunger in Guanzhong. ""As for Shu Ren, his limbs are not diligent, so I don't have to think much, but I have never heard of him asking for help. "This view that all members of society should strive to create agricultural prosperity is rare in ancient China. Jia Sixie's "prudence" mainly refers to thrift and careful calculation. In the preface, he quoted Guanzi as saying: "The solution is not enough. There are 72 miles of soup, but we have used enough. The sky is not only soup, but rain is not only millet. " Therefore, Jia Sixie emphasized "using it to save money". He noticed that the uncontrolled use of it would have a serious impact on people's livelihood. He said: "It is difficult to have a husband's wealth, and it is also difficult to use it without restraint. Mortals are lazy and have a bad rate. The law was lost, and a valley could not be boarded because of floods and droughts. H rot breaks out one after another, and the same disease can't stop in ancient and modern times. Ha ha! The hungry have a wish, and the thirsty have a sense of quantity. Eat lightly when you are full, and lightly when you are warm. Or from the harvest of the year to the accumulation, or from the excellent support of cloth and silk to the light of giving. When you fall into poverty, the reasons are gradual. So many factors comprehensively analyze the influence of thrift, which lays a solid theoretical foundation for the comparison of the interests of various "pension industries" in the text of Qi Shu. Jia Sixie's "power" mainly refers to the physical labor paid by laborers, while "labor" refers to the labor results obtained from various agricultural production activities.
In order to get the best economic benefits, Jia Sixie started from the general principle of "the right time, the right place and the right quantity", with less efforts and more success, and returned home with feelings and got nothing "(the third planting valley), and advocated" more evil is better than less good "(the third planting valley), and advocated the road of intensive cultivation in a small area. The essence of Chinese traditional agricultural production lies in the combination of land use and land cultivation, intensive management, and efforts to increase the output per unit area. During the Wei, Jin, Southern and Northern Dynasties, China entered the traditional production technology finalization period of dry farming in the north, and the small-area intensive cultivation method advocated by Jia Sixie was the embodiment of finalization technology. In order to meet the needs of traditional agricultural technology intensive cultivation, Jia Sixie not only emphasized the beneficial labor input of "Gu Duo saves effort" (the third planting valley), but also advocated the active labor expenditure of "weeding tirelessly and repeatedly" (the third planting valley). The seemingly contradictory labor input actually meets the production demand of traditional dry farming in China. The so-called "labor-saving Gu Duo" beneficial labor input is aimed at the relative comparison between labor expenditure and product benefit in the whole agricultural production process; The active labor expenditure of "never tires of hoeing the ground and going round and round" is to "start the bottom", that is, the improvement of soil properties by labor. It is advocated to improve the drought resistance and fertility of land by deep ploughing and fine harrowing, that is, the so-called "land to the tiller", which fully embodies the essence of Chinese traditional agriculture.
