Back To Eighty

Sorry, the temperature has dropped sharply in the past two days, maybe I have a cold, and people are very uncomfortable.

There is another epidemic outside, sigh, everything is gathered together, I have a little cold, and I am doing nucleic acid in the cold wind, which is even more uncomfortable.

Please take a day off today, take some medicine at night and prepare to sleep, everyone pay attention to safety, wear more clothes, don't catch a cold
