Modern food blogger Lin Zhixia accidentally traveled back to the 1932 Republic-era small town while staying up late editing videos. Penniless, she was left with only a smartphone caching a massive collection of gourmet recipes and merchant operation plans. Under the guise of 'Secret Recipe Notes,' she started from Yuelai Restaurant, introduced viral hits like bayberry soda, new-style braised food, cream cakes, pearl milk tea, spicy gluten strips, fried chicken, barbecue, hot pot, and whole roasted lamb, formed a merchant alliance, opened night markets and chain franchises, and allied with the chamber of commerce.
