Wen Niannian, a wealthy heiress weighing nearly 290 jin (145 kg), spends lavishly and indulges her appetite. Her father, Wen Zhenhong, spends a fortune sending her to Yunqi Mountain Retreat deep in the mountains to toughen her up and change her ways. Here, there are no special privileges or snacks. She must chop wood, carry water, and cook to earn her daily meals. Under Pei Lan's guidance, Wen Niannian endures four grueling months, successfully loses weight, sheds her spoiled and arrogant ways, and learns to be independent and self-reliant. She refuses to return to the city to take over the family business, choosing instead to stay and persuade her father to invest in renovating and operating the mountain retreat as a guesthouse with Pei Lan. Along the way, they overcome numerous challenges, including construction cost increases and staff shortages, while helping local villagers increase their incomes. In the process, she discovers the confidence and inner strength that money alone can never provide.
