Chinese marketers are pretty smart. It's just that the situation just lined up on today's internet-commerce and they took advantage of it. Chinese products have a hard time selling products to other manufacturing countries like US, Europe, Japan and other first world country as their products have been tagged as a below or just average compared to them it is because they value mass production rather than quality production. Thus their products aren't getting patronized by many and when they try to barter or import products to other countries most of their products are being neglected then plus the tax. Then now, the internet-commerce had a boom so they have been exempted to a hefty tax price and can produce more products without having them imported.
