Because I am a very serious, responsible and ethical person who never loses my integrity, so when I carefully read through the ten lines of the registration clause, one of the provisions stated that you can keep this ID if you publish an article within two weeks of registration. In fact, I just want to get an account to show off, to show that I was once a third-rate playwright. I originally planned to leave an empty account, but since I have to do it, I will post an article, so I have this. The joke also came from accidentally seeing it while browsing the forum in the morning, so don't complain that this thing once appeared in XX place. Meow
