Xiaoman, the daughter of a guilty minister, was sent to the harem because of a crime committed by her family, and was given the title of "Changyi", the lowest rank. She has no beautiful appearance, no talent for playing chess, calligraphy and painting, and no family support. She is regarded as a "waste" by everyone in the palace, and is ignored and ostracized. Even her dignity is often withheld.
In a desperate situation, Xiao Mo unexpectedly discovered a deserted open space next to the cold palace. The farming skills she had learned from her grandfather since she was a child became her way of survival in the harem. She reclaimed wasteland, planted vegetables, cultivated melons and fruits, and even used ancient methods to brew fruit wine and make pickles. Not only did she provide for her own food and clothing, but she also distributed the excess harvest to the palace people who were also in a difficult situation.
Her "not doing her job properly" was initially ridiculed by the imperial concubine and made things difficult by the eunuchs, but was unexpectedly discovered by the emperor who was inspecting the harem incognito. The emperor was moved by the freshness and tenacity in her fields, and was even more attracted by the sweet fruits and mellow fruit wine in her hands. Xiaoman used farming as a matchmaker, and used sincerity and wisdom to resolve disputes in the harem. From a "little farm master" beside the cold palace, he gradually became a "master Xiaoman" who could offer advice to the emperor and seek benefits for the palace people. Finally, he broke the harem's rule of "judging people by their appearance and suppressing them by their power". He planted a world of his own within the palace walls, and gained the emperor's respect and sincerity.
