Su Wan, the daughter of a criminal in the imperial kitchen, was forced to get involved in the palace because she rescued the young prince Xiao Zhaoning who fell into the water. She originally wanted to survive in a low profile, but she was called "A Niang" by the cute baby, and even attracted the attention of Emperor Xiao Chengyu. The concubine framed her, an old case was implicated, the prince seizes the heir... Su Wan relied on her superb cooking skills and her acumen to observe people's emotions, and she took the cute baby to show off her tricks: she used sugar-steamed cheese to make the Queen Mother smile, she used a crab-meal lion's head to resolve the concubine's difficulties, and she used date paste yam cake to trick out the true story of the palace maid. The emperor went from being tempted to being moved, and Meng Bao went from "liar to her mother" to sincere dependence. In the turbulent palace battle, the three gradually pieced together the truth about Su Wan's mother's injustice. In the end, the emperor's heart belonged to Meng Bao, and the injustice was overturned.
