Why does Zhang ride a donkey backwards?

Zhang used to be an official in North Korea and saved a lot of money. Later, he felt that it was not easy to be an official, and he was afraid that he would be laughed at if he couldn't do it, so he resigned and returned to his hometown. Walking, I walked to the edge of my hometown camp and saw a slim girl picking cotton in the field. Just like others, the girl listened to someone's question and replied: Zhang's land, my mother grows flowers. Miss Zhang has come to pick flowers! The girl said: pick cotton and spin. The tiller's hand is not afraid of pricking! When Zhang saw the girl's strange generosity, she got worse and worse. He said, "Huang Hua, silly girl, you are obedient and don't listen to reason." Seeing your outstanding talent, I am willing to rescue you. Only you will obey me, and you will enjoy prosperity. " . You can use a maid and never pull cotton for a lifetime! The girl is not easy to provoke, so she immediately fired a barrage: she is a flower head, she is not shy, and she is not afraid of the wind. You can enjoy the splendor, but the girls in the Zhang family don't care. My father's name is Zhang, and he is also an official. My mother is Li's daughter, and I haven't seen her enjoy any happiness. Hearing this, Zhang Yi was disqualified. This girl is her own daughter! He couldn't wait to get into the crack, but he was too embarrassed to go home. He quickly turned to practice in the mountains. Later, he turned over a new leaf and became an immortal. Zhang didn't go back to his hometown, but he always took this wrong thing to heart. He felt embarrassed to meet everyone, and since then, he has been riding a donkey with his back forward.
