Wheat field is a metaphor of Haizi's China people's heart and cultural spirit, which has different connotations and values in each poem, which is inseparable from the poet's different psychological state and aesthetic discovery. In fact, it refers to the wheat fields in the countryside, which is of course an illusion in Haizi's mind, expressing the poet's simple and warm feelings for his native land. The ground is dry and cracked, and the rice fields are wet; The wheat fields are turbulent and barren, and the rice fields are calm and rich; Wheat field is fire and snow, rice field is water and rain. Wheat fields are deeper and more painful than rice fields. All these appeal to the essence of Haizi's romantic poet, pursuing loftiness and yearning for tragedy.
Moreover, "Mai" also represents one's native land and hometown, and it is an allusion to the will to "go home".
