The Story of Pangolin

A long time ago, people in the Changbai Mountain area of ??Northeast China were prone to a disease. This disease was not a problem when people were young, but in middle age It gradually became serious. First, there was soreness in the back and legs, then difficulty in movement, and later developed into paralysis. People who suffer from this disease generally lose the ability to work and live a very hard life.

Although the Changbai Mountain area is very large, there is only one pharmacy. The pharmacy is opened by an old man and his little daughter. The old man has excellent medical skills and is kind-hearted. He never charges any fees for treating the poor, so people affectionately call him "Old Chinese Doctor". His youngest daughter is also very knowledgeable in medicine. She often goes out with her father to collect medicinal herbs. The neighbors call her Er Yatou.

The old Chinese medicine doctor has been very distressed because he has never been able to find a herbal medicine to treat this paralyzed patient. Er Yatou understood her father's concerns very well. She saw that the paralyzed patients who came to see the doctor every day went back disappointed, and she became more determined to find a medicine to treat them.

Just do it. One day, the two girls carried a basket with a sickle and a pack of steamed buns and set off. The place the second girl wants to go is Longtan. Longtan is a very dangerous place in this area. The old people said that there are often wild beasts there, and they also said that black dragon spirits live there. Many hunters dare not go to Longtan, but the second girl thought: there must be rare things that can cure diseases there. Herbal medicine, so I set out without hesitation.

The second girl walked over the mountains and ridges to Longtan. She first built a straw shed on the side of the mountain, settled down for a while, and immediately went up the mountain carrying a basket. She tried various herbs, but none worked, and she was sad. After returning to the hut, she sat blankly alone, thinking of the villagers who were paralyzed and unable to move, and thinking of her father's anxious eyes, she cried sadly, and fell asleep while crying. In the dream, a young man in black clothes came to the hay shed. The two girls were startled and asked quickly: "Who are you? What are you doing here?" The young man bowed politely and said, "I admire you very much, girl." I have more courage and want to help the girl to find a medicine to cure paralysis. "The second girl said: "What should I do? I have searched all over Longtan, but none of them are useful." The young man said: "Girl, don't worry, just stay in the shed. Just wait until daybreak to dig some kind of grass with dragon scales outside the shed." After saying that, the young man left.

In a blink of an eye, it turned dark, followed by lightning and thunder, as if it was about to rain heavily. The second girl woke up from her dream, calmed herself down, and looked outside, eh! Why is it the same as in the dream? , there is thunder and lightning. The second girl hurriedly rushed out of the shed and saw a small black dragon in the sky, which was crashing towards the mountain. Many dragon scales fell off when it hit it. The second girl burst into tears immediately. She couldn't bear to watch any more, so she walked into the grass. shed. After a while, the sky gradually dawned, and the second girl walked out of the shed according to the instructions of the young man in black in the dream. Sure enough, as soon as she came out, she saw a lot of grass with fish scales growing outside the shed. The second girl realized that these were the scales on the young man in black, the little black dragon. She was very moved and cut them off with tears. Bring a full basket down the mountain.

After returning home, the old Chinese medicine doctor mainly used this herbal medicine, combined with several other herbal medicines, to treat paralysis. Unexpectedly, the effect was very significant.

Afterwards, the second girl told the villagers what she had experienced in Longtan, and everyone was very grateful to the little black dragon. In order to commemorate them, and because the rhizome of this grass is very similar to a dragon, and the leaves are like dragon scales, and the roots grow on strings, it is extremely vital, so they called it "Chuangshanlong" or "Chuanglonggu". ;
