Copywriter Lin Wanwan has been working hard at the company for three years with a monthly salary of only 8,000. However, because a colleague mistakenly issued a salary slip, he found that he was the lowest paid person in the company. The related household received a high salary and pretended to take credit for her project, and the supervisor treated her as free labor. She collected evidence to expose the shady story in public, doubled her salary after overthrowing her supervisor, and counterattacked all the way to become the human resources director of the group. She eventually founded a consulting company to promote pay equity in the entire industry.
