I asked to write a 500-word composition about a person I admire.

Can you look at the following special "symphonies"? Chen Dang arrived quietly at Huangwan Junior High School in Hetang Town, Pengjiang District, Jiangmen City 1 Class (1), and a familiar and rhythmic sound of "swish, swish" broke the silence in the morning. This kind of sound, together with the rustling of roadside trees and the sound of bicycles and motorcycles on the road in the morning, constitutes a special symphony. Every day, when this symphony rings, it means that the wheel of history has entered a new day, and the "performer" of the main theme of this symphony is my most admired grandfather-an ordinary cleaner. Grandpa is about 60 years old, of medium build, with a hunchback, white hair and a black face. Every day at dawn, he drags the old handcart and holds the big broom, busy silently in the street near my home ... People go to school and work, and the roads are clean. I remember last year's Lunar New Year's Eve, firecrackers came and went, saying goodbye to the old year and welcoming the new year. Every family was having a reunion dinner, so I thought: Grandpa should rest and have a happy reunion dinner with his family at home! Just thinking about it, I suddenly heard a familiar and rhythmic "shua, shua" sound. At first I thought I heard it wrong, but after listening carefully, the voice was so familiar and kind. Isn't this the Symphony Theme played by Grandpa? Why doesn't he go home for a reunion dinner? Why don't you rest on New Year's Eve? A series of question marks drove me past ... hearing my question, he stopped sweeping the floor, turned his head and said with a smile, "I have already eaten." Because tomorrow is the New Year, I want to clean up the rubbish in these streets completely. If I work hard alone, I can bring a clean environment to everyone! As long as I watch everyone walking on a clean road, I feel happy! " Grandpa said, waving his broom and playing that special "symphony" in this street. Looking at grandpa's back in the dark; Look at his faltering steps; Listening to the rhythmic sound of "shua, shua", I suddenly realized: what a simple word! Isn't there a sincere heart in this simple discourse-a noble sentiment of silent dedication to people? Time, like running water, washes away the complicated things in the world. However, what Grandpa said to me and the "symphony theme" he played every day were clearly and permanently left in my mind. ...
