Locked. How funny

Yesterday I posted a very short piece of article which mentioned something about the epidemic happening everywhere nowadays. Well, not the epidemic itself, I mainly recorded the routine check and wrote down some trivial personal feelings. Surprisingly, it turned out the article was locked soon after it was shown online. It's not like I said anything illegal or politically wrong. I only recorded that I did a routine check which was city-wide and that the epidemic seemed to get worse when it got colder. As far as I know, I really hadn't said or meant to express anything illegal or politically wrong. However, this very short piece of article was just locked. How funny it is!
