How about the detection of Yunyan mysterious garden

The most direct method is to scan the QR code to detect the authenticity. Just turn on the code scanning function in the mobile phone WeChat and scan the QR code on the side of the trademark: after scanning the code, enter the 6-digit verification code at the opening of the small box as prompted. If it is a genuine cigarette, a prompt will appear: the QR code you scanned is the first verification. If it is not a genuine cigarette, the scanned QR code will not respond or display "Non-first verification".
