Stick to examples that don't know how to innovate.

My home is in the countryside, and I cook with corn husks every day. There is a bug in the corn husk, which is 1.5 cm long and 0.4 cm wide. There is a washing powder box in front of me, made of plastic, rolled into a cylinder, with a height of 20 cm and a diameter of 10 cm. There is a little washing powder there, and there is a bug on the floor. Sometimes I go to the edge, come back and move on. I watched it for a while, and then I left when I had enough. This was found the night before, but the bug was still on the washing powder box the next morning. It didn't climb, but it didn't die. At this time, I thought, maybe it was tired of climbing and couldn't climb any more. Maybe it realized that it would climb down forever and return to the original point. I reflect that if we humans don't have the spirit of innovation, we will be afraid to try and innovate like that poor bug. Walking and not walking are the same, there is no way out.
