At present, I haven't seen Ren really do this. Even drawing a circle (standard) can only be done by a few math researchers and some math teachers, let alone drawing a square in Chinese painting with the other hand. I'll tell you a short story: Today, the teacher asked at the beginning of class, "Who can draw a square?" Who can draw a circle? "Aren't these extremely simple questions a piece of cake? The teacher asked two students to draw, and they finished it easily. Students think about it: these children who have never been to school can, but we can't?

The teacher said solemnly, "Let's continue to draw squares and circles. The rule is: one hand draws a circle and the other hand draws a square. " After listening, the students all said in unison: "Dizzy". Wu Jie volunteered to draw on the stage, only to see that her right hand drew a square and her left hand drew a circle, and both hands didn't listen. She drew a rounded corner on the square and a straight line on the circle. She still stops from time to time, and her movements are not skilled at all. It seems simple to draw with one hand, but drawing with two hands at the same time is completely different. Later, the teacher asked us to practice drawing on paper by ourselves. My hands are like two stubborn donkeys. I want him to go shopping, I want him to go shopping. I drew many different shapes: some like wooden windows, some like doors, some like mountains, some like caves, some like boards, some like clouds … I was dazzled, but I didn't draw any of them well. Now, do you understand?
