What are the physical descriptions of the old man who picks up garbage?

1. He doesn’t seem to have any clothes. He puts a dirty and torn sack on his body every day, and the skin that cannot be covered is exposed, with a layer of moisture on it due to being out of bed for a long time. A few and knotted nails. Every time I passed by him, he would smile stupidly at me, showing his uneven row of yellow teeth. But when other students see him, they always take a detour. At this time, he will open his sack like Batman, revealing his thin and dirty body to the sunny and healthy classmates.

2. His hair, which had not been taken care of for a long time, stood upright and messy. Time had drawn deep wrinkles one after another on his dark face, making him look older than his actual age. Many eyes that had long since lost their clarity were looking at the garbage under them with cloudy eyes. Their mouths were tightly pursed, and they were holding an iron rod-like thing in their hands, and they were constantly turning over it.

3. The tattered clothes on the body are full of patches, the yellowed shirt is covered with dust, the uneven trouser legs on the left and right spread over a piece of brightly colored land, and the pair of gray feet on the The threads of the old shoes had long been tied, revealing a row of dark black toes trembling in the air.

He was carrying a large bamboo basket on his back. Through the not-so-tight bamboo holes, one could vaguely see the contents inside, including iron cans, iron rods, old paper and wood, and perhaps some other things.
