An article in Reader is about a boy who showed others the way at the intersection. He was very moved a long time ago, but he can't remember his name. Please help.

There is a light rail in Tuen Mun, Hong Kong, with a street on one side and a hillside green space on the other. The platform is open, and there is a fare swipe machine for passengers to swipe their cards. Standing on the platform watching idle flowers and weeds, watching passers-by in the building, a tram came in a moment, and the vibration of the track spread far away in the high sky, feeling very leisurely.

Take the light rail to Tin Shui Wai with friends, and take a child with you on the way. It was a chubby boy, wearing baggy shorts, with an Octopus card around his neck and a black musical instrument box in his hand. The bag on his shoulder must be music. He should go home for piano lessons or piano lessons on Saturday. It's interesting to see him with a serious expression and an important task, so we pointed to his box and asked, "oboe?" Ask again: "Clarinet?" First he stretched himself, then he couldn't, and a smile appeared on his bulging cheeks. We asked for the third time, "violin?" He nodded hard and guessed it. So we sang an etude of Caesar, the basic violin lesson, and became friends with him. He didn't speak, just laughed. We had some tacit understanding with him, and then the light rail arrived.

The transfer situation is more complicated than expected. There are many different routes on the same platform, as if the Tin Shui Wai we are going to is not on any route. So I called my new friend and asked him for advice. He pondered for a while, and his chubby fingers designated a point on the road map, indicating which bus we should take; After climbing along the line for a while, it stopped and showed us where we were; After a pause, his finger jumped to another route, meaning to change trains; Then quickly crawl to Tin Shui Wai and stop, indicating that you have reached your destination. After showing the way, he walked away and kept his distance from us. We didn't know he was in a car with us until the car came. The crowded crowd blocked our view. Several times, I saw him turn to look for us with an anxious expression on his face, but after seeing us, he immediately turned to look at the back of the man in front. When we arrived at the transfer station designated by him, it turned out to be a hub station. After getting off the bus, he showed us a direction at a distance. We followed his instructions for a few steps, but he turned and ran to the opposite platform. He tried to alternate his round legs and lift the violin case over his knees to avoid bumping, which was very difficult. The cloth bag on his shoulder kept beating his body, and we couldn't help but stop. He pointed out again with his hand as he ran, letting us know that we were wrong. Finally, he led us to the platform on the right and stood at a distance. The station platform is bustling, and he and we are like meeting or knowing each other in the vast sea of people, and gathering and parting are impermanent. The light rail to Tin Shui Wai stopped, and the little boy saw us get on the bus and left with confidence.

Judging from the violin he carries with him, the little boy can't be over ten years old, but he can take a ride to piano lessons alone, and he can also give directions to strangers, and he has become an adult's mind. From beginning to end, he basically didn't speak, perhaps because we didn't understand his Cantonese, or because we laughed at his Mandarin. He said a few key words in English. Only the melody of the violin etude "Kaiser" communicates for us, so that we can meet by chance in this world.
