Su He, a peasant girl, married into a declining prince's mansion with a copy of "Essential Art for Elevating the People". Faced with the crowding out of the back house and the emptiness of the treasury, she discerned that the abandoned "Nine-winding Drinking Pond" was actually the remains of an irrigation canal. Using the waterwheel as a guide and the terraces as a pen, she turned Houmen's backyard into a vibrant "mulberry fish pond", using agricultural wisdom to eliminate waste and increase production and income. Don't fight against concubines, just work hard. From "female farmers" to "concubine women's agricultural technology school", Su He used the wisdom of the field to create a new path for the Hou Mansion, and also let the ancient agricultural science shine with the light of governing the family and the country.
