What does "wheat" represent in Haizi's poems?

Mai Di: It is a metaphor for the Chinese people’s mind and cultural spirit. It has different connotations and values ??in each poem. These are different psychological states and aesthetic discoveries from the poet. Inseparable, in fact, it refers to the wheat fields in the countryside. It is of course an illusion that appeared in Haizi's mind, expressing the poet's inner simple and warm feelings for his hometown. [15] The wheat fields are dry and cracked, the rice fields are wet; the wheat fields are turbulent and barren, while the rice fields are calm and fertile; the wheat fields are fire and snow, while the rice fields are water and rain. Wheat fields are more profound and painful than rice fields. These appeal to the essence of Haizi's romantic poets, who pursue the sublime and yearn for tragedy.
