After reading Plum Blossom Soul, the ancient poem about homesickness that comes to my mind is:

There are several plum trees in the corner, and Ling Han is blooming alone. I know it's not snow from afar, because there is a faint fragrance coming. ——Wang Anshi's "Plum"

You come from your hometown, so you should know about it. Leaning in front of the window tomorrow, have the winter plum blossoms bloomed yet? ——Wang Wei's "Miscellaneous Poems"

The plum blossoms are three points whiter than the snow, but the snow loses the fragrance of the plum blossoms. ——Lu Meipo's "Snow Plum"

The tree at the head of the inkstone washing pond at my house has blossoms with faint ink marks. Don't let anyone praise you for the good color, just leave the pure energy to fill the universe. ——Wang Mian's "Mo Mei"

The sparse shadows are slanting across the clear and shallow water, and the faint fragrance floats in the moonlight dusk.

————Lin Hejing's "Little Plum in the Mountain Garden"
