The source of this poem comes from the seven-character quatrain "Late Spring is Things" written by Ye Cai, a poet in the Southern Song Dynasty. The whole poem is as follows:
Shuangwaque wrote a book case, and a little bit of Huayang entered the inkstone pool.
Sitting in a small window watching Zhouyi, I wonder how long spring will go.
The appreciation of this poem, simple and light in style, describes the scene of ancient intellectuals studying hard in spring. Among them, the combination of static and dynamic techniques is used to set off the silence of the protagonist studying hard at the window with moving scenes such as "Waque Calligraphy Case" and "Huayang Entering the inkstone Pool". It is this quiet scenery that breaks his inner peace, thus giving the feeling that spring is fleeting.
