Crutch Original: On that day, I bid farewell to my hometown and gave my mother a crutch, which supported my mother's life and entrusted me with infinite hope. She bowed her head to her mother, oh, that's the image I left her; It walked straight, and the sound immediately reached my ears.

The first section is confession. In the second section, the author imagines the arc at the top of the cane as a poet bowing his head to pay tribute to his mother; Starting from the straight shape of the lower part of the cane, it is said that the mother walks, but the cane walks; I don't mean that I am far away from my mother, but that my voice echoes in my ears. These are two typical details. Obviously, with the help of the image of "walking stick", the poet described the affection in detail from the front with concise pen and ink, which made people feel the eternity of affection.
