1. After entering someone else's store on Alibaba, open the company album. If it is a real company, there will be photos of machines, factories, workshops, offices, etc.

2. Continue to find and supply products in other people's stores on Alibaba. If it is single, then the chance of being a real manufacturer is much greater, because a real manufacturer cannot supply too many products. If there are dozens or even hundreds of product types, it goes without saying that it is basically a dealer. It is difficult to arrange too many manufacturers.

3. Continue to find the contact information in Alibaba's store. There is a contact information on it. You can call and talk. You can ask some technical and professional questions to determine whether the other party is a manufacturer. If the dealer will only deal with you.

4. Continue to scroll down to the contact information to see the specific map address. You can see whether it is an industrial zone through Baidu Map Street View.

5. See if there is an icon of on-site certification. This is officially recognized.

6. Make an appointment with the other party and say you want to visit his factory to see how he reacts. If it is nearby, you can go for a visit. Face-to-face interviews are most effective.
