If I can find the source of goods, I think selling perfume and clothes is the most profitable, followed by selling beautiful underwear, diet pills or health care products and shoes. There are many people browsing these things, as long as your things are unique and attractive enough.

And be sure to name good things so that people can find them easily.

It's hard for people who run second-hand baby shops to mix on Taobao now, because everyone relies on word of mouth. It is impossible to sell diamonds when selling second-hand goods. You'd better look for online approval or find a source that can get the goods cheaply ~

As for the auction, I think things like jewelry are better. Generally speaking, the price difference will not be too big, and things that are too expensive will not lose money. If no one photographs them, you will feel very distressed. What can be photographed is clothes.

Ordinary old amoy friends like a price ~ not too expensive.

Good luck:)
