I want to open a local clothing store. All the goods are purchased from Taobao, which means that the original goods will definitely involve some brands and so on. Is this illegal?

The general legal channel of foreign trade is to export to domestic sales, so the factory will not be so laborious to directly and secretly handle the tax declaration. So there is no formal procedure. If you sell locally, small cities generally don't check, so don't be too high-profile, especially if there are regular distributors of your brand in your city, and they may report it when they know it. If you are worried, you can cut the label and sell it, which does not involve brand significance.
