If you want to engage in recycling legally, you need a business license of a pawnshop, but the relevant procedures are very troublesome. I guess it's hard for you to approve. Now the recycling is hanging outside, and there is basically no formalities. The relevant departments also turn a blind eye. Seriously, it is impossible. Also, if you recycle goods without a license, you should register the identity of the seller. In case the Public Security Bureau receives stolen goods and comes to you, you can cooperate to avoid your loss. If you don't register, you will be in trouble.
