Liu Wang, a native of Shandong, learned to iron with his father when he was 16 and began taking over his father's business. Seeing that his son had grown up, the old blacksmith Liu told Liu Wang to go out and make a break. Hearing his father's words, Liu Wang brought the blacksmith and a few buddies to Hebei. At that time, northern Hebei was still relatively peaceful, and the people who had suffered from the war needed to rest and recuperate, although the Song Dynasty had allocated a lot of land to Liao.

Liu Wang had been playing iron in Liao for three years. One day, he heard that Liao was going to war with Great Song again, and his family sent a letter asking him to go back and marry. Liu Wang had to pack up his belongings and set foot back on the road to Shandong with a few buddies who came out together. Passing through Chicheng, Hebei Province, he encountered heavy rain and had to find a shop to stay at. The shopkeeper saw a few blacksmiths coming, took out the farm tools and other household items that had been used up for many years, and asked them to add some more steel. Liu Wang agreed. The next day, in a clear sky, Liu Wang asked the guys to set up the blacksmith furnace and start ironing. Unexpectedly, the furnace could not stop when it started. When people from Shili Baxiang heard that several Shandong blacksmiths had come to Chicheng, they brought all the farm tools that needed to be added to their homes. Therefore, Liu Wang has done more and more work.

One day, the guys were working in the store. Liu Wang went shopping and met a young and beautiful girl in a grocery store. After the girl saw Liu Wang, she lowered her head and smiled. This smile didn't matter, Liu Wang's heart was moved. So he walked up to the woman and asked her name, and the woman smiled and told him her name was Xinyue. Liu Wang wanted to ask a few more questions. At this time, an old lady came out of the grocery store, glanced at Liu Wang and asked who Xinyue was. Xinyue's face turned red and said she didn't know. The old lady pulled Xinyue and walked away, and after a few steps Xinyue turned around and smiled at Liu Wang. Liu Wang hurriedly walked into the store and asked the owner of the grocery store who the old lady was just now. The boss said he didn't know, but only heard that she came to take refuge in Daming Mansion.

Liu Wang returned to the store and kept thinking about the new moon. In the evening, he went to the grocery store alone, hoping to meet the new moon again, but he didn't see it after waiting a long time. He hoped to see that beautiful girl again. Heaven paid no attention, and the new moon finally appeared. As soon as she saw Liu Wang, she ran over and said, "I know you have been waiting for me these days, and I miss you too. You can wait for me at the fork outside the city at night." Then she left. Liu Wang wanted to chase after her, but when he saw the old lady again, he hurriedly turned to hide, but he was so excited that he didn't know what to do. At night, he went to the fork of the road. At the intersection, he really saw the new moon waiting there. Seeing Liu Wang, Xinyue said, "Come to my house, my old lady has gone out, and I am the only one." Liu Wang thought about it and agreed, and he stayed at Xinyue's house for the night. The next day, at dawn, he didn't want to leave, and Xinyue said, "Then you can stay for a few more days." Hearing Xinyue's words, Liu Wang was very happy, so he stayed and spent the day with Xinyue, and slept with Xinyue at night. More than ten days passed without realizing it. One night, he heard a knock on the door, and Xinyue said in a panic, "It's broken, my old lady is back, you should go quickly." Liu Wang was still reluctant to bear Xinyue, but he was still pushed out of the house by Xinyue. Liu Wang turned around and wanted to take a look at Xinyue's house again, but unexpectedly found himself in the wilderness. There was no family, just a cemetery with a tall elm tree on it. Liu Wang was so shocked that he broke out in a cold sweat.

In the middle of the night, he couldn't identify the direction at all, and he didn't know the way back. Just as he was in despair, Xinyue suddenly appeared in front of him. Xinyue said, "Close your eyes, and I'll send you back." Liu Wang hugged Xinyue and said, "I know you're a ghost, but I still want to be with you." Xinyue also shed tears and said, "Your fate and mine are over here, and God's will cannot be violated. Let's continue our relationship in the next life." Liu Wang closed his eyes with grief, and then he felt himself floating up, and then he heard a "bang" and fell to the ground. When he opened his eyes, he saw his store. After entering the store, the guys were both surprised and happy, and asked him where he had been for the past few months, which made everyone find it very hard. The work here was done, and it was cold, so it was time to leave for Shandong tomorrow. Liu Wang said nothing, and the next day he went back to Shandong with the guys.

Time flies, and it has been almost twenty years since Liu Wang returned to Shandong in the blink of an eye. One day he finished ironing, and suddenly felt a little sleepy, so he closed his eyes and planned to sleep for a while. Suddenly he saw New Moon. New Moon was still as young and beautiful, and said to him, "Liu Wang, who do you think this is?" Liu Wang looked at an eighteen or nineteen-year-old girl standing behind New Moon. The child looked at Liu Wang shyly. New Moon took the child and said, "I'm not calling him father yet." The child called out with a kiss, and Liu Wang was very beautiful in his heart. The child was very beautiful and looked very obedient, and he was more likable than the children in his own family. New Moon told Liu Wang about the pain of these years of separation, and Liu Wang took his daughter's hand and said, "This child looks just like you." New Moon said to Liu Wang, "Come back and repair the door of the house. It rained that day, and Lei broke the courtyard door." Liu Wang agreed.

The new moon pulled the child and said, "My old lady is out, I have to go back." After saying that, he left with the child. Liu Wang woke up and found that he had just had a dream. He sat up and thought about the things in his dream. It was the first time in so many years that he had dreamed of the new moon. He went to the stove and pulled the bellows. After a while, the fire in the stove burned the red iron. He picked up the hammer and struck the iron. He was almost forty years old, and his body was still very strong. After the iron was struck and went to quench, a strange thing happened. In the basin, an ancient elm tree appeared on the water. The tree was exactly the same as the one he saw twenty years ago, but the trunk was obviously split open. He put down the hammer and went home to tell his wife that when he went to Liao, he made a wish in a temple, and today he dreamed that they asked him to return the wish. As soon as his wife heard this, she let him go.

Along the way, Liu Wangxiaoxing stayed overnight. When he arrived in Chicheng, Hebei Province, he hurried to find the ancient elm tree. He raised the stove and made an iron hoop to turn the elm tree up. On the night after the elm tree hoop, he saw the new moon again. The new moon stayed with him for one night and said to him, "After you return to Shandong, let your child study hard and practice martial arts. In the future, he will not be a thing in the pool. Our fate is over, and we will only meet again in 1,500 years." After saying the new moon, he disappeared. Liu Wang opened his eyes and found himself sleeping under the ancient elm tree. The next day, he set off for Shandong.

Liu Wang lived to the age of ninety-six and died without illnessHis youngest son, Liu Tang, later became a hero of Shuibo Liangshan, and died in Jiangnan during the war to pacify Fang La. His grandson later won the examination of Jinshi, and he was also a man of all ages. He fought against the invasion of the Golden Army with Yue Fei, the anti-gold hero of the Southern Song Dynasty, and was an official until the end. Until now, the ancient jade is still there, in Shangma Mountain Village, Samtian Township, Chicheng County, Hebei Province. The tree is nearly thirty meters high, and it takes five or six people to hug it. It is the first jade in the west of Beijing. In summer, the branches are lush and the crown is like a silver umbrella, and the snow is proud in winter. The iron hoop forged by Liu Wang has been embedded in the tree body, which is vaguely visible.
