Xu Muyuan impersonated her colleague Song Wanning by using her lost top-tier membership card, throwing around three hundred thousand to act wealthy at the Song family's restaurant, and instigated colleagues to ostracize Song Wanning. Song Wanning remained calm; when checking out, the reported-lost card instantly became invalid, Xu Muyuan was unable to pay, and her deceit was exposed in public. Refusing to accept defeat, she then colluded with unscrupulous rivals to spread rumors and smear the restaurant. As the successor to the catering business, Song Wanning used her wisdom to dismantle the rumors and called the police to protect her rights. In the end, the evildoers received severe punishment by the law, and Song Wanning successfully defended her family's honor.
