The salty fish heroine, who comes from an ordinary background and just wants to make money for retirement, unexpectedly enters the palace and becomes the nanny of the unpopular young prince. She adheres to the principle of "do more and make more mistakes, do less and make fewer mistakes, and if you don't do it, you are right". She just wants to live a stable life and leave the palace after saving enough money. However, in a palace where everyone is scheming and everyone is an actor, her "abnormal" Buddhist behavior was over-interpreted by everyone.
Passing a piece of candy to a crying concubine was regarded as a signal of alliance in times of need; taking a nap when sleepy was regarded as a sign of wisdom after seeing through a dead end; humming a tune unintentionally was regarded by the emperor as a code word to predict the current situation.
The heroine herself was confused throughout the whole process, complaining wildly on the inside, but as calm as an old dog on the outside. The more she wanted to lie down, the more people around her thought of her as a peerless expert who had no plans and a clear mind. The concubines of the various palaces regarded her as a "walking cheat" and competed to win her over; the crazy criticizing emperor regarded her as the only "explanatory flower" who could see through him, and he only loved her. Without knowing anything about it, the heroine went from being a little nurse to becoming the only legend in the harem. In the end, she carried enough gold and silver to buy several cities. In the eyes of the emperor who said "I love the country more than you", she was thinking about whether to eat Sixi meatballs or braised pork elbow for lunch today.
