I sprained my waist, and I had a day of pain yesterday, so I got up and went to the computer desk to code words. Today it is even stricter, and it is difficult to sit up. I went to the hospital for a check-up, and the doctor said that it was a strained ligament. So I hung the needle several times before I came back. When I came back, I wanted to code words, but it was too late. I can only say sorry to everyone. Tomorrow Xiaochao will definitely make up the chapter, here I apologize to everyone......
