Need help to read the tutorial from your website.

Hello @dyc87112 , I think this is a really good tutorial. I want to learn spring boot but your tutorial is in the Chinese language, I am converting all the pages into English using a google translate extension. it is ok. but when I click on Read the full button to read the full article it opens one qrcode dialog. then what to do I don't understand. when I scan it opens one URL on my mobile. and there is no login-related functionality on the website. Could you please guide us on how to read the full article?
