Ploughing and Weaving Map is meticulous and full of artistic appeal, which depends on Lou Ai's long-term observation experience of agricultural production and superb artistic attainments. When he was in office as a county magistrate, he traveled all over Nanmenfan, Hengshan Fan, Fangyuanfan, Qixiang Fan, Duishifan, Zhuting Fan, Aogan Fan, etc. around the twelve townships in Qianxian County, went deep into the fields and corners, and went in and out of farmers, so he had local experience. What is especially rare is that the images it left on the screen are engaged in agricultural production, leaving precious materials for studying agriculture, especially agricultural tools, which cannot be obtained from written materials. For example, the "Irrigation" and "Yiyun" pictures depict the scene of pumping irrigation with buckets, orange peels and dragon bone carts. What we can see from the picture of Harvest is a tense rice cutting scene. "Weaving" and "Climbing Flowers" draw the plain looms and flower looms that were already used at that time, so that people can more vividly understand the development of sericulture and textiles at that time. Many of the farming and weaving knowledge and production tools recorded in it have been used to this day.
