Hey, Lin Dongyu, I haven't seen you for a long time, I miss you so much. This is our 430th day together. We are two thousand kilometers apart. It seems that for the two words of different places, there is something special to say. Hey, Xia Bai, this is our 430th day together. The midterm exam is coming soon. I have been reviewing very hard. Your club activities are also so tiring. I really want to be by your side. We can meet in 60 days.
