Why does Zhang ride a donkey backwards?

Zhang is one of the ancient myths and legends in China. According to Zhang, he was an assistant in the era of Emperor Yao. By the early Tang Dynasty, he had lived for more than three thousand years. And was summoned by China's first empress Wu Zetian and Tang Xuanzong for many times, but was evaded by Zhang Feign Death.

There are also differences about the legend of Zhang riding a donkey upside down. The first legend is that Zhang was said to have been 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 came to the edge of my hometown camp. I saw a slim girl in the distance, picking cotton in the field. I chatted with others and flirted with that girl. I didn't know that the girl was my own daughter until she was taken away by the girl. I can't wait to get into the cracks and feel embarrassed to go home. I quickly turned around and went to the mountains to practice. 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.

There is a folk song called Cowherd in Hebei Province, which is a household name. Everybody knows that. Who will come to Zhao Zhouqiao to repair it? Who will leave the jade railing? Who rode the donkey bridge? Who rolled a ditch with a trolley? Master Lu Ban restored Zhao Zhouqiao, and the sage left a jade railing. Zhang rode across the donkey bridge, and Chai's car rolled into a ditch. This is a very interesting legend.

According to legend, in ancient times, a skillful craftsman named Lu Ban built a big stone bridge on the river in the southern suburbs of Zhaozhou City overnight. Fairy Zhang heard about it and rode a donkey to see it. On the way, he met the car of King Chai County, and Zhao Kuangyin pulled the car, so the three of them came to the riverside in the suburbs to see the bridge. After seeing Zhao Zhouqiao, all three people secretly marveled at Luban's exquisite skills. In order to test Lu Ban, Zhang and Lu Ban bet that if the three of them can cross the bridge smoothly and the bridge does not fall, they will ride the donkey backwards from now on. When three people stepped onto the bridge, Zhang turned to cast spells, collected the sun, moon and stars, and put them in the wallet. Chai Daguan and he also used magic to gather the five mountains together and quietly put them on the unicycle. Due to the surge in load, the bridge could not bear it and began to shake. Seeing this, Lu Ban jumped into the river, raised a hand and tried his best to hold the bridge, which turned a corner. Zhang threw in the towel face to face and began to ride backwards. Wheel prints and donkey's hoof prints were left on the bridge deck, as well as knee prints left by Master Chai after he slipped. At the bottom of the east side of the bridge vault, Lu Ban left a big handprint when he held the bridge hard.
