How can blind old people write a composition when they see their son-in-law?

It was noon on a Sunday, and there were no clouds in Wan Li. In an alley, I saw an old man in rags squatting in the corner, holding a flute in his hand and blowing it gently on his mouth, with a broken bowl next to him. His bronzed face, wrinkled face and blind eyes make people feel sorry at first sight. Seeing his pitiful appearance, I gave him all my only 12 yuan.

In the afternoon, the sun shines brightly on the earth as if to scorch it. I passed a restaurant and saw the old man take off his fake beard and hair just now, with one foot on the stool and one hand on his knee, shouting, "Come to the noodles, hurry up!" " His blind eyes are wide and round now. I'm short of breath and hate blurting it out. The next day, he pretended to be an old singer and begged for money in the corner. I didn't want to see him again, so I turned my head to the other side angrily.
