2. Appreciation of quatrains
In quatrains, quatrains depict a vibrant natural beauty and show the vitality of early spring; The second sentence of the poem, from oriole to egret, shows that the visual space is open, from bottom to top, from near to far, so that the vitality seen and felt by the poet fills the whole environment, thus showing the prosperity of early spring from another angle. The last two sentences of the poem, the scenery seen outside the window, are linked with "Wu Dong", which shows the poet's homesickness after the dust settles. The poem Jueju not only expresses the poet's longing for the passage of time, but also reveals the meaning of loneliness and boredom.
