Class reunion, a place to relive memories. Perhaps the years are passing by like water, and those familiar faces in my memory have been covered with a thick layer of gray. Perhaps the days are like years, looking forward to, looking forward to, the north wind sending snow to reunite with classmates. The former squad leader may now just be sitting at the gate of the park selling tickets, but the former King Pi may have been doing business for several reincarnations, and he was living a respectable life in his childhood. We agree that on this day every year, we will gather under this tree, no matter it is windy or rainy, or there are more terrible bullets. In these difficult days, can we continue to have a class reunion that belongs only to us?
