Su Shi, the first of three poems on poetry appreciation

(1) "Frost" highlights the old state of "poet with white beard and scattered hair", and implies the bumpy fate of his repeated relegation in his life.

(2) "Zhu Yan" originated from wine, which was originally "wine red", "joy" reflected the son's concern for his father, and "smile" reflected the poet's feelings of being frank and philosophical in his twilight years (it can also be analyzed that "smile" is the contrast of writing sorrow with joy, and it is the author's self-mockery and contains frustration that has gone through many ups and downs).
