This poem was written in 1954, when the poet had left the mainland for six years, and his homesickness was increasing day by day. Perhaps it was an accidental flipping through an old book, and a locust leaf caught in the book jumped into the eye and touched the most sensitive string in the poet's feelings. So the poet's heart trembled and his feelings stirred up waves, so he used this locust tree leaf to express his homesickness.
This poem takes "a leaf of Sophora japonica" as the image, expressing the poet's homesickness and yearning for his hometown. From the beginning of Sophora japonica leaves to the end of the season eager to return to the fragrance of Sophora japonica flowers, it echoed from beginning to end in one go. Like the last poem, it uses the artistic technique of chanting things and expressing feelings.
