Jia Shu is not from The Book of Songs, but from The Ode to Oranges in the Nine Chapters of Chu Ci. Its content is: After Emperor Jia Shu, Oranges come to serve Xi. I was ordered not to move. I was born in the south. Deep-rooted and difficult to migrate, more determined. The green leaves are brilliant and gratifying. The first sentence means that the oranges bred in your world are born to adapt to the local water and soil.
On the surface, this poem is a tribute to Chenpi, but in fact it is the poet's confession of his ideal and personality. In the form of four words, the poet created a beautiful image of dried tangerine peel by personification, and described and praised dried tangerine peel from all sides to express his firm will to pursue good quality and ideals. Jiashu mentioned beautiful trees in his poems, implying the poet's love and loyalty to the motherland.
