At the urging of her father, Lin Ziqing returned to Shanghai from Singapore to manage Pengfei Department Store. However, she found that with the advent of the experience economy and the popularity of e-commerce and social media, customer expectations and consumption behaviors have undergone earth-shaking changes. The traditional service industry model has been difficult to improve customer satisfaction and loyalty. She tried to reform Pengfei Department Store, allowing customer experience concepts and design to penetrate into every process and detail of corporate management, using big data information mining to assist decision-making, and at the same time conducting comprehensive O2O integration, hoping to increase the loyalty of Pengfei Department Store customers. But no matter how glorious Lin Ziqing's past was, she realized that it would be even harder to make everyone in Pengfei Department Store customer-oriented. The test she faced was far more difficult than she imagined. On the other hand, her life has also suffered various tests; is her wealthy marriage really as happy as it seems to the outside world? Is her stepmother really as virtuous as she appears? Is her father a kind person again? Will her good friends who have always supported her be able to accompany her until the end? All of this made Lin Ziqing feel like he had hit rock bottom.
