Is the company that can't be found on Baidu formal?

To know whether a company really exists, you should go to the local Red Shield website to check the status of the company's business license. Baidu's failure to find it is not necessarily irregular. Some companies can't find it without their websites or online information. For example, to query the company's business license in Guangzhou, Baidu should search Guangzhou Red Shield Information Network, and then enter the company name to see the company's business license information.
