What does it mean to send Guizhou's verification code on the cloud?

The verification code sent by Guizhou on the cloud is a scam message. During the epidemic, many people's mobile phones will receive some SMS reminders that it is time to do nucleic acid testing, or there is something wrong with the nucleic acid testing report. You need to click on the link to query, enter personal information, and have a verification code. These are all scam messages. Don't believe it.
