Hangzhou Xinhua three-body electronic flow sends me a text message. Is it safe to link QR codes?

It's not safe. Don't visit the QR code link through SMS, which may cause property damage.

The link in the short message may contain Trojan virus, which will automatically obtain the highest authority of the mobile phone, thus stealing the funds in the bank card bound in the third-party software. The information such as receiving the prize and swiping the bill in the short message itself is fake. Adding the contact information of the other party will only step into the trap of the liar and then let you transfer money for various reasons.
