In the mountains around Zouping, Shandong, there is an inconspicuous hill. In a village near the hill, there is a family surnamed Wang. His parents passed away early, leaving only two brothers to live together. The older brother is called A Xiao and the younger brother is called Ah En. Although A Xiao is only two years older than Ah En, the eldest brother is his father, A Xiao loves his younger brother everywhere, while the younger brother, Ah En, has been pampered since childhood. Not only is he lazy, but he often does wrong and causes trouble. For this reason, Xiao educated A En a lot and controlled A En more and more strictly. Unexpectedly, A En hated his brother because of it.

One afternoon, when the sun went down, Ah Xiao and Ah En came back from work on the mountain. When they passed by a dry well, Ah En said to Ah Xiao, "Brother, I heard a voice talking in the dry well." Ah Xiao believed it and looked around the dry well. Unexpectedly, Ah En pushed him into the dry well from behind.

Ah Xiao fell into the dry well and shouted at the bottom of the well, "Brother, stop joking, find a rope and pull me up!" Unexpectedly, Arn said, "Hmph, think beautifully, just stay inside!" As Arn spoke, he threw a large stone into the well. It turned out that Arn had always thought that his brother controlled him too strictly, so that he could not do whatever he wanted with those friends. Today, he pushed his brother down the well, and finally let out a bad breath in his heart. When Arn returned home, he swept away all the valuable things in the house and left his hometown.

Perhaps Ah Xiao's fate should not have been extinguished. There was a pool of soft mud at the bottom of the well, which was covered with dead leaves. After Ah Xiao was pushed into the well by Ah Yan, it seemed that he fell on a pile of cotton, and the big stone thrown by Ah Yan did not hit Ah Xiao. At first, Ah Xiao thought that Ah En was just angry with him and would come back to save him in a while, but the wellhead was already starry, and Ah En had not come to save him, so Ah Xiao shouted a few times, hoping that someone could hear him and save him. But now it was dark, and people had gone home, and no one could hear his voice at all.

Ah Xiao stayed at the bottom of the well in a daze until midnight. Just as he was drowsy, he suddenly heard a voice talking in the well. Ah Xiao listened and faintly heard a voice saying, "There is a big pine tree about five and a half miles east of here. There is a spring under the pine tree, and there is a gold plate covered on it. After lifting the gold plate, you can dig a well to solve the drought here..." At this time, another voice said, "Hey, be quiet, let the Jade Emperor hear about this, and we have to blame us for leaking the secret." Ah Xiao also heard the two whispering about the serious illness of Li Yuanwai's daughter in the city, unless...

The next day, after dawn, when people passed by the well, they heard Ah Xiao's cry for help and rescued him. According to the news from the well, Ah Xiao walked east, rushed to a place five and a half miles away from the well, dug under a big pine tree, and indeed dug up a gold plate, lifted up the gold plate, and spring appeared. This is good, because now it is a severe drought, and all the nearby springs are dry. With this new spring, the problem of drinking water for people is solved.

Ah Xiao sold the gold plate above the spring, and then used the money from selling the gold plate to do good deeds such as repairing bridges, paving roads, and helping the poor. Ah Xiao suddenly became a famous good man nearby.

On this day, Ah Xiao went into the city to look for Ah En, because Ah Xiao often missed him after Ah En left. As a result, the younger brother could not be found, but Ah Xiao saw the notice posted by Li Yuanwai in the city to treat his daughter. The notice said that Li Yuanwai's daughter had a strange disease, and the famous doctors in the city could not cure it. Li Yuanwai saw that his daughter's condition was getting worse day by day, and he was so hurt that he had to post a notice seeking someone who could cure his daughter's strange disease. The notice said that whoever could cure Li Yuanwai's daughter's illness, Li Yuanwai would give him half of the family's land. In addition, if a young man is cured of his daughter's illness, he will marry her to the young man; if it is an old man, he will let his daughter consider him a godfather, and in the future he will die like his biological father.

Ah Xiao took notice and came to Li Yuanwai's house. Ah Xiao told Li Yuanwai that he could cure Miss Li's illness. After that, Ah Xiao asked Li Yuanwai to take him to the back garden of Li's house. Next to a big elm tree, Ah Xiao stopped and saw a piece of fungus the size of a black gauze hat in the shade of the big elm tree. Ah Xiao picked up the fungus and let Miss Li take it after boiling.

After drinking the medicine, Miss Li recovered quickly. Li Yuanwai did not break his promise and married his daughter like flowers and jade to Ah Xiao, and married half the land.

Besides, after Ah'en took away the family property, he went out to eat, drink, and gamble, and soon ran out of money. At this time, he heard that his brother had married Li Yuanwai's daughter and became a rich local family, so Ah'en rushed home in disgrace and confessed his mistake to his brother. Ah Xiao did not blame him, but treated him as always.

Unexpectedly, Ah'en's nature did not change, he just wanted a sum of money when he went home. But although the family had thousands of properties, Ah Xiao was very strict, and Ah'en had to think of other ways.

When Arne learned that his brother could easily make a fortune and marry a beautiful wife, he knew the secret because he fell into a dry well, so Arne decided to travel to the dry well, maybe he would have better luck than his brother.

Arne tied a rope around his waist and put himself into the dry well. Arne sat smugly at the bottom of the dry well, waiting for good luck to come.

At night, Guozhen's voice came from the well: "Someone leaked the secret, the Jade Emperor is going to blame us, it seems that we can't stay here any longer." Then another voice said: "We can't take advantage of this person for nothing. Now there is a person in the well, it should be the person who eavesdropped on us last time. I didn't expect him to come back, do you still want to hear more secrets? In that case, let's screw his head off!"

When Ah En heard that, he knew that the person who spoke had misunderstood him, so he quickly shouted, "Grandpa Immortal, that person last time wasn't me, it was my brother, and my name is Wang En!"

"What an ungrateful thing!" Arne heard a sneering voice in the darkness, and then two dark shadows flew away from the well. Just as he was surprised, he saw a dark mass seal the well.

The next day, people found that the dry well had disappeared, and the original place had become a hill. What was even more strange was that whenever someone passed by this hill at night, someone could always faintly hear someone talking, saying something like "I'm ungrateful, I'm ungrateful." From then on, people called this mountain "Ungrateful Mountain."
