(Food + farming + street stalls + ensemble cast + building a fortune + cozy everyday life) No System or pocket dimension, slow burn
Jiang Yun opened her eyes to find she had transmigrated into the body of a famously ugly young woman in the countryside of an ancient era. She had an incompetent older brother and two frail, undersized younger siblings. Before she could even process what had happened, the sight of her family's nearly empty rice jar made her faint.
To keep them from starving, Jiang Yun brought her family together to open a modern-style snack stall in ancient times. Candied hawthorn skewers, hot and sour noodles, jianbing, century-egg congee, grilled skewers in flatbread, fried chicken strips... If she could think of it, she sold it! From a snack stall to a breakfast shop and then a high-end restaurant, she somehow turned the Jiang family eatery into a nationwide chain, while also raising her three brothers to become pillars of the nation!
The former fiancé who had once scorned her for her looks came desperately crawling back. Before Jiang Yun could answer, a jealous man stood guard at the gates of the Jiang residence, knife in hand, and said darkly, “You think you're worthy of speaking to her?”
P.S. The male lead appears later on. The main storyline focuses on the heroine's career.
The author's setting is quite good, but it's a pity that the ending was rushed.
