The ground is covered with green shade and flying swallows;
A curtain of clear snow curls in plum blossoms.
——This is a couplet inscribed by He Shaoji in the Qing Dynasty, "Looking at Pines and Reading Paintings in the Lion Garden in Suzhou". This couplet cleverly and naturally integrates green shades with swallows, clear snow and plum blossoms. On the surface, it seems to be a literati's description of the scenery in the two seasons of spring and winter. In fact, it expresses the quiet and noble pursuit of life by literati and elegant people. People have endless reverie and endless charm. In the couplet, the author not only pursues the vigorous artistic conception of spring full of vitality and the revival of all things, but also describes the cold winter as "a curtain of clear snow curling in plum blossoms". The sharp contrast between red and white, the snow on a sunny day is gradually melting, The plum blossoms appear one after another, pregnant with vitality and full of poetry and painting.
