Modern marketing director Lin Wan finds her account suspended overnight, leaving her drowning in debt. A message suddenly appears on her phone screen: "This account has been ruined. Would you like to start over?" She presses restart and wakes up as a merchant family's concubine-born daughter whose engagement has been broken off, with nothing left but an empty, rundown stall. With no capital and no connections, she puts secondhand goods into cloth bags and sells them for ten coins each, establishing a rule: if a bag's contents are worth less than ten coins, she will refund double the difference. From guaranteed minimum-value refunds and three-tier lucky bags to membership stamp cards, she faces everything from trade guild exclusion to merchant alliance crackdowns. Using modern business strategies, she gradually transforms her shabby stall into a renowned brand on Jinli Street.
