The beloved seventh daughter of the Gu family is revealed to have been switched at birth. The real heiress who returns home is seen as a useless rich girl—lazy, uneducated, and unwilling to study. The elite circle in the capital waits to watch her become a joke. But she shocks everyone by mastering fortune-telling, physiognomy, and feng shui. She becomes a favorite among celebrities, a consultant for criminal cases, and a guest of honor to the richest families. Even more surprisingly, she helps her six brothers win back their ex-wives and children, rewriting the fate of the Gu family.
