Lin Mo, a network security practitioner (network engineer → security sales), was reborn back to himself when he graduated from college in 2015. After graduation, I was introduced by my cousin Zhou Cheng to work as a network technician at Shute Technology (a data center construction integrator), and at the same time, I signed up to upgrade from junior college to bachelor's degree to improve my academic qualifications. During the study process, I met Zhao Yiming, an employee of Hengyu Information Technology Co., Ltd., And entered Hengyu Information Technology Co., Ltd. Through internal recommendation. With the industry memory and experience of the next ten years, he had the foresight in the yet-to-explode network security industry. He started as a grassroots salesperson and worked his way up the ranks within Hengyu - key account manager, industry line leader, sales director, and company vice president. He promoted the company to cash out after listing, and finally entered the AI security track as an angel investor, completing a counterattack from grassroots to financial freedom, and from a worker to an investor.
