She wasted her whole life, only to be defeated in the end by a mistress with bulging goldfish eyes. Her PhD husband personally sent her to the crematorium...
The heroine and the mistress from her previous life are both reborn.
Reborn from the ashes, the widowed Xia Qingqing, the heroine, navigates life with a horrible mother-in-law, who was the mistress in her previous life, and crushing poverty. To make ends meet and raise her daughter, she puts her pride aside, bats her eyes and acts cute, and curses like a shrew. Fearless of ghosts or gods, she draws on the strength of a modern woman, builds a fortune, and finds true love along the way.
The heroine fights her way through that era with sheer force of personality, thrives, and makes it to the top.
