Before becoming a dragon, Suolongjing and Jiaolong generally lurked in rivers, which were called hidden Jiaolong. After thousands of years of practice, they have become dragons. In order to walk into the sea, they will cause flash floods and bring disasters to the world.
Therefore, Lock Longjing is also called Lock Jiaojing. According to legend, the earliest Lock Longjing was that Dayu ruled the world, and it was made in Yuzhou, Jinan, Chongqing and other places. The reason is very simple, that is, lock up jiaozi to avoid flooding when taking jiaozi.
After Dayu, there were many lock longjing, the most famous of which was the lock longjing in Cangxiang, Nanjing.
Legend has it that when Zhu Yuanzhang established the Ming Dynasty and made Nanjing his capital, he had a dream. In the dream, an old dragon king said to Zhu Yuanzhang, You are finished. Fighting every day makes me feel uncomfortable. I want your country to perish.
Zhu Yuanzhang was frightened, so he quickly invited Liu Bowen for help.
Liu Bowen, as we all know, is a risk-averse. Daoism and five elements are good. He decisively transported 72 goblins, dug 72 wells in Cangxiang and nearby alleys, and put a thick, big and long chain in one of them until it reached the bottom of the well.
Then he said to Zhu Yuanzhang, "Your Majesty, don't worry, this dragon has been nailed with 72 nails and entangled in chains. It can't do whatever it wants. " .
Lock dragon cave, hang Cambridge, lock dragon cave and lock longjing are similar.
After all, some legendary dragons who broke the dogma were locked in caves, which was equivalent to closing a small black room, but for a long time. There are legends of Lock Dragon Cave in Anhua, Hunan, Changdao, Nanchang, Jiangxi and Dali, Yunnan.
Let's say the dragon life in The Journey to the West is better. If you break the dogma, you can just cut it off and live a good life. It is better to die early than to be imprisoned for a thousand years.
It's the same in Cambridge. In order to prevent the dragon from causing floods, a dragon-cutting sword was hung at the bottom of the bridge, which can deter evil dragons.
Ancient Japan was deeply influenced by China culture, so there were many similar legends in Japan.
Use, in the final analysis, whether it's Locking Longjing, Locking Longdong or hanging in Cambridge, it's a manifestation of ancient water control and waterproof culture in China. Do you think it is useful? Locking Longjing does have a certain effect.
Suolongjing went down to the underground river and met rising water, and groundwater gushed out from the wellhead. If it is too violent, it will cause floods, so putting a thick chain can prevent blowout to some extent.
As for the legend, there will be rumbling in the Lock Longjing, such as dragons singing. It is estimated that the underground river will naturally make a sound when it surges against the rock stratum. Coupled with the large echo in the well, it is not surprising that the sound becomes rumbling.
