Lin Wei is recognized as a gold medal negotiator in the industry, with an annual salary of seven figures, and the contracts in her hands can fill half a conference room. On her thirtieth birthday, she received a call from her hometown. Her grandmother was seriously ill and her last wish was to see her get married. She flipped through her address book, and in the list of recently contacted clients, she found the man with whom she had a red-faced argument at the negotiation table last week. Three days later, she took the marriage certificate back to her hometown for business, thinking that this was just a contractual marriage where each got what he wanted. Until late one night, when she came home from overtime work, she found her "contract husband" sitting on the sofa at her home, flipping through the competing product plans she was going to compete with tomorrow. He raised his head and asked her: "Ms. Lin, do you need me to teach you negotiation skills?"
