Qiao Jinniang's parents passed away the moment she came of age.For the sake of inheriting a restaurant, she had no choice but to ‘recruit’ a husband who would take her family name.Who knew that her husband, who looked like a banished immortal, was an ingrate? He snatched her child away and left behind a divorce letter.Qiao Jinniang became the butt of every joke in Lin’an City.

Back then, when the marchioness gave birth to her, she encountered a robber.

Even His Majesty showered her with praise. She was pampered by everyone in the Marquis' residence.Those long-tongued women in Chang'an City said sourly, "So what if a woman gets pampered at home?
