Recently, the epidemic situation in Qingdao has been somewhat severe, affecting not only Laixi but also Chengyang, and most importantly, it seems that even Licang, one of the three central districts, has reported cases, which is quite alarming.
However, after all, we are now in the third year of dealing with this, so it's not too bad. I remember back in 2019, there was a case in our neighborhood, and the entire area was sealed off, but for someone like me who rarely goes out, the impact was minimal.
What I mainly want to say is that Qingdao has now started comprehensive testing. Without a nucleic acid test, you can't go anywhere, so today, I went out to get tested, which took up quite a bit of time. Plus, I didn't have any drafts saved. Therefore, I'll update later on. Just refresh this chapter a bit later to see the correct content, probably around 1 or 2 a.m.
