The whole poem "Ode to the Opening Class" written by Zen master Huang Lian in the Tang Dynasty is: It's hard to get rid of dust and labor, so do it tightly.
How can plum blossom fragrance be without biting cold?
Translation of works:
It is unusual to get rid of dust and labor.
It takes effort.
There is no cold,
There is no fragrance of plum blossoms. This poem uses plum blossoms to bloom in the cold season and exude fragrance, which is a metaphor for the situation of hard exploration and epiphany, thus expressing the poet's advice to the world to be as noble as plum blossoms.
