The ONE person who is making enough to feed her kid . I don ' t buy it no pun intended . If she sells higher end stuff she might . I have friends that do jewelry selling on wechat amber , those vine bracelets from Tibet , the white bead necklaces and other , sorry I don ' t know how to translate these lol that seem to be living off this . Most of them also sell on Taobao or in a market though too , and also do some assembly beading necklaces , etc . A few years ago doing was also at least marginally profitable you know , going to Korea , buying expensive cosmetics and other goods and taking them back to China to sell but I ' m not sure how it is now that customs are a lot stricter . Anyway , while OP ' s sockselling student might only make a few hundred rambos a month , it ' s totally plausible that someone is feeding her family with it if she ' s frugal .
