Why can my friend change girlfriends every day? He rents a Rolls-Royce and uses it to sell stockings at the night market. Every time he sets up, the area is always packed, and he provides a free changing room inside the car. The girls go inside to put on the stockings, take photos, then come out—almost never haggle over the price, and often voluntarily add his WeChat. He makes thousands of dollars in a single night—and meets new girlfriends in the process.
