How can I know which enterprises are in a city? Such as Shanwei

There are about two kinds. One is to go to the industrial and commercial bureau and other administrative departments for consultation, but the policy is not clearly disclosed or there are no acquaintances. The second is to check by yourself, including keyword search on the internet, so that generally older people will have records; Or ask some people who are familiar with the local situation. I don't know what information you want to know about these enterprises. If it's just a name, you can even read the tax notice on the bulletin board of the IRS, which is also a convenient method.
