I bought the products on Taobao and then sold them in my own place.

It depends on what you sell. Legally speaking, as long as what you sell does not infringe on other people's intellectual property rights, you can. At the same time, the small shop you opened is legally qualified. To tell the truth, because many things sold on Taobao, such as clothes, are highly imitated, if intellectual property rights are really infringed, the first batch are these sellers, and now everyone turns a blind eye. What are you afraid of?
