2. Cricket was a toy that boys often played in those days. In the eyes of the post-80s generation, not catching crickets is not enough to call it childhood. In today's era when reinforced concrete is not so common, it is also very common for crickets to enter the house. Many old people have superstitious views about crickets entering the house. So does this phenomenon indicate good luck? It doesn't matter if you can't find it. The chirping of crickets on summer nights is also quite interesting. It seems that I have instantly returned to the time when I was a child playing with insects and cicadas in the back hill, and there is a feeling that memories reappear in time.
