Recently I started to draw something on small cardboard and boxes. Due to the epidemic situation, it became troublesome to get in and out of the village, so I simply locked myself in the studio and tried to kill time by drawing and writing, which was all right. I could still buy food on JD.com, but what about if I ran out of the frames? If the epidemic lasts for a long time, it would be possible that no one makes frames anymore. And I accidentally saw JD.com's cardboard boxes scattered all over the place, which seemed a waste to throw away. It suddenly appeared to me that I could draw on the cardboard, even if there were no frames. Since then, I began to pay attention to things around. I kept the cardboard and plastic sheets in case I need them. What cannot be used under extreme conditions? And I threw less garbage. With enough rice for half a year and a large pile of cardboard, I felt quite relieved. Isn't this what life is like? You can only judge the circumstances at each step, pretending to be someone living underground.
