Just out of school, a sound of erhu drifted into my ears. Looking in the direction of the voice, I saw a lot of people surrounded by the iron fence. Out of curiosity, I squeezed into the crowd and saw an artist playing the erhu.

The artist wears a dusty straw hat, which is irregularly woven with a lot of messy hay. The center is round and high, which intentionally or unintentionally covers most of the artist's face. I can only vaguely see his black and white stubble sticking out his chin like a steel needle, which looks thick and hard. Wearing a dark brown tunic suit, the cuffs are broken and patched. Wearing a pair of brown dusty pants. Wearing a pair of black cloth shoes with white background that should be an "old man" on his feet, he sat on a stone covered with plastic bags. There is a dirty basin at his feet, with a lot of rust on it, and there are several dimes, one yuan and two yuan in it.

There is a faded erhu with many cracks on the artist's knee. Zhang looks like an old bark, holding a Hu bow in his right hand, pulling it stiffly and mechanically, and pressing the strings from time to time with his left hand covered with blood vessels on the back of his hand. Some unknown tunes came from Hu repeatedly, and faint white powder floated from time to time on the bowstring.

With a curious heart, like other students, I crouched down and looked up, only to see the artist's dull bronze face, wrinkled corners of his mouth and eyes, as if carved by a knife, and his eyes seemed to be open and closed. At this time, a classmate put money into a small basin evasively, only to see his upper and lower eyelids suddenly open, emit a light, then close it again, and then lean down deeply and silently to thank him, but the piano never stopped. Bang, it turned out that a classmate threw a coin on the edge of the iron plate, bounced off and rolled away. The artist's head suddenly moved and his eyes were fixed on the rolling coin. It was not until the classmate picked up the coin and threw it into the iron basin again that he closed his eyes again.

Seeing these scenes, I put my hand into my pocket several times, but I remembered what I read in the newspaper. ...
