"Afforestation is like a tree, quality is not wood, lofty and shady", which is the image description of the shape, quality and posture of banana by predecessors. Banana is tall and straight, its posture is rough and natural, and its leaves are as green as silk and picturesque. In the meaning of banana, there are both the rudeness of northerners and the delicacy of southerners. This is like Jia Tanchun's character in A Dream of Red Mansions, which has both the boldness of northerners and the gracefulness of southerners. Jia Tanchun even claimed to be "my favorite banana" and called himself "a guest under a banana" after opening a poetry club. Visible, banana is actually a character symbol of Jia Tanchun.
