An Internet model poses for photos in an apartment in Hefei, East China's Anhui Province. With online shopping business growing rapidly in China, Internet models, who are generally untrained amateurs or students, are in great demand, considering the high cost of hiring professional models in online shops. Internet models don't necessarily have to be tall or good at catwalks, but they need to know how to match clothes to look good and have animated facial expressions for posing for photos in dozens or even hundreds of outfits. Their earnings are said to be quite pale in comparison with professional models, however.
