Su Wan, a palace maid from a rural area, was chosen as a substitute because she looked exactly like the late Emperor Bai Yueguang, but she refused to be a "shadow". Relying on the skills of farming and identifying medicinal materials she learned from childhood, she opened a vegetable garden in the harem and grew rare vegetables and medicinal materials. Not only did she improve her life and that of the lower-class palace residents, she also used farm food to please the queen mother, used medicinal materials to save the emperor, and gradually resolved the concubines' frame-ups (such as poisoned wine, and blaming for theft). Through "farming wisdom" (observing details and patiently dealing with things), she was promoted from a maid in the laundry bureau to a promise and a permanent presence, to a nobleman, a concubine, and finally a queen. She broke the fate of being a substitute, gained the emperor's sincerity, and used the farming concept to reform the harem, so that there was no longer only fighting within the palace walls, but full of life.
