Li Zicheng fought all his life, fighting in the south and in the north. According to historical facts, when he entered the city of Beijing, he was "riding a black barge horse in a felt hat" (see "Ming Ji Beiluo" volume 20), and his horse riding was also called "oolong horse" (see Yao Xueyin's "Li Zicheng"), and he proclaimed: "I will be the son of heaven right away." (See "The Continuation of the Writings", vol. 1). The horse made great contributions to the "Great Shun Emperor General Li Zicheng" (Comrade Mao Zedong Zedong wrote to Mr. Li Dingming), and the horse was also connected with Li Zicheng's heroic reputation. Therefore, it is rumored that when Li Zicheng was a post guard and a groom in Yinchuan, he formed an indissoluble bond with the horse.

During the Ming Dynasty, there was a famine in the countryside of northern Shaanxi for many years, and the government imposed heavy taxes and miscellaneous taxes, and the people were struggling to make a living. After Li Zicheng's father was loyal and died, he had nothing to rely on, so he wandered to Mizhi City. happened to meet Yinchuan Post to recruit post grooms, and Li Zicheng was happy to apply. Yi Cheng saw that Li Zicheng had high cheeks and deep eyes, was tall and strong, and was agile and good at walking, so he agreed to come down. Li Zicheng can get more than 20 small copper coins every month, but it is better than the wandering life, so he feels a little at ease. Since then, the official document has been delivered, and the horse gallops in the Yansui Road, and the nearest one goes to the Suide Station and Yuhe Station eighty miles away from Mizhi City, and the far one sometimes reaches Yulin Town and Yan'an Mansion.

At that time, the Yinchuan post was located on the horse horn platform in the current Mizhi City, Yinchuan post is also called "horse horn station", and the earth station is also called "horse number" to continue to be used today, but the remains of the current post station have disappeared because of the age. Legend has it that there were dozens of horse sheds built in those years, and the stone troughs in the shed were connected, and the horse piles outside the shed were in order. Every day, the stagecoach is vibrating, wagging its tail and neighing, and the postman and the groom are calling each other, which is a unique scene. Li Zicheng was first a horseman and then a post man, and after delivering the official documents, he stayed in a few tiled houses next to the stable, and after a day of hard work in the cold and scorching sun, sometimes he went to the Mawang Temple with his post boy friends to relax. So far, there are still tile houses in the folk because Li Zicheng, the "true dragon son", has lived, so there is no legend of flies, mosquitoes and fleas.

Mawang temple is connected with the horse number post, the seat is north to the south, there are five main halls, in front of the hall door is the corridor corridor, the couplet on the corridor pillar is "the magic point blesses the thousand horsemen, and the holy virtue has given the heroic soldiers. The door is "looking at the world, the palm of the hand", and the horizontal eyebrows: "fragrant lotus". There is a tall statue of the prince of Ma on the platform in the hall, with three heads and six arms, holding a sword, and posing with a fierce and vicious face. There is a clay horse under the stage, there is a galloping trend, and there is a horse leader holding the reins in front of the horse. Zicheng entered the hall and was often willing to touch the mud horse, patted the back of the horse leader, and said to the post man's friend: "You and I Li Zicheng have the same fate, and they will suffer from cattle and horses." The friends also said, "We're not the same people!", and the patriarch sighed.

One day, everyone was sighing, suddenly heard the noisy voices outside the hall, and saw that under the guidance of the post and the temple owner, several people carried two corpses with wooden boards, and many onlookers gathered behind them, and came straight to the hall. I am not surprised that I am friendly with all the people, I don't know what is going on, I just need to see it carefully. I saw the two corpses carried into the temple, and they were laid on the ground with their hands and feet, lying on their backs. The temple owner took out four large bowls from the box, buckled them on the hands and feet of the deceased, and cut off a bundle of horse's tail and placed it between the legs. He immediately lit incense and burned paper, knelt under the statue of Ma Wangye and prayed: "Today, there are two people, Liu and Zhang, who are sent to the god of Ma Wangzun, so that they can be turned into stagecoaches in the next life, and the big bowl shows that their hooves are strong and their legs are thick, so as to contribute to the royal transmission of official documents." Then he prostrated in thanksgiving.

Li Zicheng and his fellow posters heard one of the onlookers say: "Yinchuan Yiyi and the head of the Mawang Temple and the abbot have made a decision, if there are lonely and widowed old people who cannot be buried, they can report to the post office, so that they can turn horses in the next life, and they can get a little burial expenses." When he heard this, he burst into tears, sighed and said, "The poor suffer while they live, suffer when they die, and if they have the next life, they will become donkeys and horses." ”

All my friends said yes. They hid their tears and watched as the bodies were carried away and buried. Since then, Li Zicheng secretly hated the royal government for being unkind and unjust, oppressing the poor, and it was terrible.
