Red Cherry Green Banana was a famous line in an ancient poem from the poem "Jin Se" by the Tang Dynasty poet Li Shangyin. The meaning of this poem was that the color of the cherry was red, and the leaves of the banana were green. This sharp contrast made people feel very happy. This poem was widely quoted to describe the contradictions and comparisons in love, life, nature, and so on. It could also be understood as a sigh of the short life and the impermanence of the world. Cherry and banana were two distinct plants. Red and green were their most obvious colors. The dichotomous opposition of red and green made this poem full of vitality and beauty, making people feel the charm of life and nature.
