It was too ordinary this morning, and nothing happy happened at all. When I walked on the street, I saw a lonely old man sitting on the street, holding a piano in my hand, making a very nice sound.

One autumn morning, I packed up as usual and went out. It was too ordinary this morning, and nothing happy happened at all. When I walked on the street, I saw a lonely old man sitting on the street, holding a piano in my hand, making a very nice sound.

So I was attracted to it. In fact, there are many artists on the street, including young, old, men and women. I always just glanced at it and went there. Today, the piano held by this old man attracted me. The lower part of the piano looked like a gourd, and the top was like the horse-head fiddle in our country, but it was a sheep's head and two long sheep's horns. You can tell at a glance that this is a local ethnic musical instrument.

And the old man also sang while pulling and singing. I can't understand what he sang, and I feel like monks in big temples in China are chanting scriptures. I put 30 yuan in the box in front of him, and then he immediately stopped playing the violin, greeted me and saluted me (I think it might be a military salute, because he was wearing a military cap). I wanted him to continue to play a "Bridge" that I was more familiar with, so I hummed the main theme for him. The old man seemed to understand it, and nodded happily and said: OK Serbian , OK Serbia, then took off his military cap and gestured it a few times. I took it with me and gestured a few times, and then put it in a regular manner. It seemed to tell me that he was a soldier when he was young. Although I didn't fully understand what he said, I understood what he meant. He missed his youth very much. I suddenly wondered whether he had participated in the war against NATO in 1999. The old man put down the piano in his hand, took out an instrument like flute , and told me Serbia and Serbia. I nodded and said OK OK, the old man started to blow, (unfortunately it was not the "Bridge" I want to listen to).

A melodious flute sound has taken away his emotions, maybe he was in his youth, or maybe he was in his barracks. He played very seriously, I listened very seriously, there was no other person around, only I quietly admired the old veteran and his beautiful flute sound, and I didn't feel like giving him a thumbs up. I was in a surprisingly good mood during the following shopping. I went in one bookstore, cloth store, and clothing store one by one. Although I didn’t buy anything, my soul was greatly satisfied and I was very happy.

That's why I said that the surrounding environment can determine your mood. I don’t know if he told me so much because I am a Chinese, or if he knew that China was a good friend of Serbia, his reaction was enough, which was enough to show that the friendship between China and Serbia was indestructible. Friends said it was.
