Please go back to the story about the Yangtze River.

In ancient times, in the Qingjian cave outside Xumi Mountain, there lived two twin dragons, one green and the other yellow. They hate evil and often fight the "shadow" on the coast of the East China Sea.

One year, there was a great drought on earth, and heaven was badly needed in the land of mountain gods. The Tathagata knew that Qing Huanglong knew the world well, so he sent them to the world to eliminate disasters and rescue people.

Soon, Huang Qing Erlong discovered that it was the second demon "ghost" that caused demons and grandchildren to spread around the world and set fires everywhere. It also makes magic hide a kind of "fire" in everyone's heart, doing evil to each other and disturbing the cool world on earth, so many people worship it and follow it.

Qinglong and Huanglong are determined to exorcise evil spirits for mankind and reorganize the right path on earth. They disguised themselves as two monks to drive away people's evil thoughts and heart diseases in the name of treating diseases and exorcising evil spirits.

Due to the poison of "shadows", people at that time generally suffered from a disease called "Yan". Only by plotting against others, or doing something that harms others and benefits themselves, can the pain caused by this disease be temporarily alleviated. Qinglong and Huanglong, disguised as monks, let people take some cinnabar, pearls, sea baths and so on, and teach people to recite a spell to dispel the "fire of boils." After this kind of treatment, many people recovered their kindness and alleviated their pain, and people spread the news. Three months later, thousands of people lived a normal life according to this method, and people also told stories.

The Shadow, who lives on the coast of the East China Sea, heard that someone had broken their magic, so she sent their two right-hand men, Crocodile Essence and Toad Essence, to find out the truth. Toad essence is full of evil things. It persuaded the simple and fierce crocodile elves, dressed as two patients to treat diseases, mixed among a group of people and came to the place where the monks lived. The toad essence, which has been tempered for thousands of years, looks from afar. In the shade of a tree, two monks let out two beams of green and yellow light on their heads, knowing that the other side had a lot of connections, so they had a plan. It tells the crocodile essence that they are two little gods and need not be put there. Crocodile essence was furious. Isn't it cheap for you to pick it out by yourself with toad venom? So he quickly revealed the original god, opened his mouth like a hay knife and rushed at the two monks.

Qinglong and Huanglong knew that two goblins were coming, but they just kept silent. Just then, I saw the crocodile essence suddenly coming straight at me. One of them hit a marble-sized dragon ball, aimed at the crocodile essence, and then knocked it to the ground with one punch. The crocodile essence was about to turn over and run away, when his hand turned, another monk grabbed it and split its brains. Toad essence took this opportunity to drive a gust of wind and hurried back to the coast of the East China Sea, telling the "shadow" that it was Qinglong and Huanglong.

The "ghost" was furious and kissed the magic 50 thousand to challenge. Qinglong and Huanglong told all the cured people not to come out, so they rode on the clouds to face the "shadow" in the air. Qinglong and Huanglong each performed their magic and fought against the magic weapon for seven days and seven nights.

Since ancient times, evil has been invincible, and "ghosts" can't escape this justice. I saw Qinglong and Huanglong win one after another, and two demons were defeated one after another.

Seeing that there were fewer and fewer magic soldiers, the "ghost" was unwilling to fail, so he discussed a vicious idea: the "ghost" and the two demons used magic to gather all the poisoned people and follow them wholeheartedly, under their control, in two long snake formations, north and south. From a distance, they look like two giant snakes rolling on the ground. They tried to destroy the blue-yellow Erlong and the people who escaped its control.

Qinglong and Huanglong fought with the magic weapon for several days and nights, exhausted. When they saw the shadow trying to destroy the people they rescued, they were determined to protect them. So regardless of safety, Qinglong and Huanglong turned into two cold rivers that were not connected with each other, and went to meet two fire dragons respectively. When the river comes into contact with the "fire snake", the magic grandchildren are dragged into the river by a huge whirlpool, and it is difficult for people who follow the "ghost" to escape. After three days and three nights, two salamanders were driven out more than a thousand miles away.

Qinglong and Huanglong gradually pressed the "fire snake" under their bodies. Because the two dragons paid too much, they hurt their vitality and gradually embedded into the ground, forming the present Yangtze River and Yellow River.

Today, the descendants of the Chinese people on both sides of the Yangtze River and the Yellow River are still nurtured by two great rivers.

Shuang Bian cut off.

According to the Northern Wei Dynasty. Cui Hong's Records of the Former Qin Dynasty, during the first year of Xiaowu in the Eastern Jin Dynasty, after Fu Jian, the former Qin Dynasty, unified the north, he decided to mobilize millions of troops to destroy the Eastern Jin Dynasty and unify all China. Fu Jian called ministers to discuss, and many ministers disapproved. One of them, Shi Yue, dissuaded him and said, "From the astrological point of view, this year is not suitable for going to the South. What's more, according to the risks of the Yangtze River, the King of Jin won the support of the people. We might as well stick to our national strength for the time being, produce an entire army, wait for the internal looseness of the gold, and then wait for an opportunity to attack. Fu Jian said disapprovingly, "The astrology is not credible. As for the Yangtze River, Fu Cha, the King of Wu in the Spring and Autumn Period, and Sun Hao, the Lord of Wu in the Three Kingdoms Period, all suffered from the natural hazards of the Yangtze River and finally had to perish. Now I have nearly a million troops. Just throwing the whip into the Yangtze River is enough to cut off the river. What are we afraid of? "Fu Jian regardless of the opposition of ministers, decided to send troops to attack Jin, personally led an army of eight hundred thousand, forcing him to attack the Eastern Jin. Eastern Jin generals Xie Xuan and Xie Shi led 80,000 soldiers to resist the enemy. Fu Jian underestimated the enemy and tried to attack quickly with the advantage. However, it was stubbornly resisted by 8 Jin Army, and was defeated by 8 Jin Army at Feishui. Since then, the former Qin dynasty has never recovered. Later, the idiom "the whip is cut off" evolved from the original text "My people throw a whip into the river, which is enough to cut off its flow", and it is used to describe the large number and powerful force of the army.
