Two nails to read the answer

1. The old man who is dressed in rags but looks calm

The old man is very thin, with veins standing out on his neck

His wisps of white hair

2. He sympathizes with the sad life experience of the old man, but does not degrade his personality because of his rough life experience and has great backbone.

3. I think the old man took the things in those food bags. Although he didn't say anything, he knew in his heart that this was the care of the people in the community. When he took those foods, the old man should have a lot of expressions, or be full of gratitude, or sigh infinitely (or more good people). Maybe his eyes were full of tears.

4. The old man is a man of great backbone and stubbornness. He maintains his dignity in his own way, is self-reliant and has a lofty personality. Hehe ~ is a group of people worthy of respect and social attention and care.
