The Legend of the Yellow River

It is said that a long time ago, the ancient Yellow River was a wild horse that was difficult to tame. It ran at will, like a grinning monster, roaring day and night. , devouring thousands of hectares of fertile land. With millions of mountains gnawing at them, the Hui Han people on both sides of the Yellow River can only live a life of slash-and-burn farming on the tops of the mountains and at the bottom of the ditches.

At that time, Ningxia was not a flat plain, but was covered with overlapping green mountains and criss-crossing ravines. There was no flat field, and no field could be filled with water from the Yellow River.

Legend has it that there are several households of Hui and Han people living on Niushou Mountain. Several generations of them carry water at the bottom of the mountain and farm on the top of the mountain. The old and the young are busy all the time, but they don't have enough to eat and don't have enough clothes to wear. No one can bear this torture for a long time.

One year, an old man named De, who was over seventy years old, opened a melon orchard on the mountain and planted some cucumbers. He got up early every day and went to the Yellow River to water the cucumbers. His shoulders were swollen and the soles of his feet were peeling. He carefully cultivated the cucumbers, and they grew tender and sweet.

The old man De was tired that day and fell asleep lying on the garden door.

As soon as he fell asleep, he dreamed of a white cloud floating in the sky. Gradually, the white cloud turned into a white-bearded imam, trembling his silver beard, and said to Mr. De: "Today there is an imam." You have to pay attention to the two strong winds. There is a yellow wind at noon, which can make cucumbers wilted; and there is a black wind in the afternoon, which can make cucumbers fall off.

When the old man woke up, he saw that the white-bearded imam was no longer there. Instead, he saw that the yellow wind from the north was blowing all over the sky and came to Niushou Mountain. I felt very sad that a year's hard work had been wasted, but when I thought of the white-bearded imam's words, I didn't move.

At noon, a black wind passed by, shaking the mountains and shaking the leaves, and dropped a layer of leaves. Another layer. The old man saw that the cucumber was about to fall to the ground. He was so angry that he picked off a small and wilted cucumber and threw it into the Yellow River. It was like a god cutting it with a knife. Chu Di saw the bottom of the river. When the old man swooped down, the river water suddenly closed up again. The old man was tired and hungry. He sat on the river bank, blinking, and the golden flowers were dancing, feeling dizzy. I don’t know anymore.

At this time, the old man De heard the white-bearded imam say again, "This cucumber is the key to conquering the Yellow River. It can stop the Yellow River from flowing, and it can also make the Yellow River listen to others. But now the Yellow River is tormenting the two Iblis, Huang Feng and Black Wind. You cannot be impatient, you must be patient, and you must work harder. Next year, you plant another garden of cucumbers. When the cucumbers are ripe, you pick the biggest one and throw it into the Yellow River. At that time, you walked into the cave at the bottom of the river. You could pick out the jewelry, get the grain, and have a sword that could slay dragons and demons, and tame the Yellow River. Wherever you pointed, the Yellow River water would flow. ”

The next year, the industrious old man from Germany planted another garden of cucumbers. He was not afraid of the long journey and did not hesitate to sweat, carrying water from the Yellow River to water the melons. The hard work paid off, and in the end, the garden There was a three-foot-long cucumber inside, which looked like a key. The old man happily slept in the melon garden day and night until the melon was ripe.

On this day, the weather was so clear that there was no cloud. The old man picked off the three-foot-long cucumber, said "Tasmi", and threw it into the Yellow River. At this time, he heard a roar from the Yellow River, and a long crack was opened, and the stones on the bottom of the river could be clearly seen. Chu. The old man went down to the bottom of the river and saw a hole near the river bank. There were all kinds of pearls and agates in the hole. When he just walked out, he heard a strong wind roaring and waves rolling on the river. After a wave, the old man Gerd picked up his sword and slashed dozens of swords at the black whirlwind and yellow whirlwind.

At this time, the Yellow River broke. Gradually, the old man remembered the white-bearded imam's instructions that this sword could conquer the Yellow River. He became enlightened and thought: I will let the Yellow River fill the trenches and level the mountain ridges. Holding two swords, the old man marched towards the Yellow River. The water of the Yellow River stopped flowing suddenly, as if there was a Great Wall in front of it, but it was getting higher and higher, which looked really scary from a distance.

Three days later, it reached Liupan Mountain in the south and Liupan Mountain in the west. As far as Helan Mountain, there was water everywhere, leaving only a few mountain peaks. Only then did the old man draw his sword and let the water of the Yellow River flow forward.

From then on, Ningxia became a mountainous place with deep ravines. The Hui Han people living on both sides of the Yellow River relied on their hard-working hands to dig canals and cultivate fields, and lived a happy life. "The Yellow River cannot clean it", "I will never die until I reach the Yellow River"
