Is Wu Kaizhan's haircut for my father a good poem?

This is a good poem. Between the lines, we can see the author's helplessness to the ruthless years. Time is a knife that kills pigs. He has turned a capable middle-aged man into a quiet and obedient old man. The author recalled the details of getting along with his father in the past. Compared with now, he is sighing and lamenting his father's efforts. He is sad because his father is old. He wants to go back in time. He wants to see Almighty Father again. He can't bear to watch his father grow old and show his deep affection for his father and son.
