At an art seminar, the painter Li Ming showed one of his latest abstract paintings. The painting is colorful but the lines are messy, and the combination of picture elements seems illogical. At this moment, Zhang Qiang, who is also a painter, walked over, the corners of his mouth rose slightly, and said in a tone of disdain: “Yo, Li Ming, your painting is really unique! I think you just spilled the paint on the canvas at will and finished it, right? Can this also be called art? According to your logic, I can find a cat to step on the paper a few times, maybe it can become a master work! ” Li Ming blushed and retorted: "This is my unique artistic expression. Don't talk nonsense if you don't understand. ” Zhang Qiang reluctantly refused to forgive, and continued to taunt: "Unique? I think you don't know how to draw anymore! What else to say about artistic expression, your preference is really peculiar enough, and it is estimated that you can appreciate this kind of messy thing by yourself. ”
