Are there dragons in Suolongjing, Beijing?

Longjing Shiplock under Beijing New North Bridge. Legend has it that he was chained by an old dragon king. When he took over the chain enterprises of the Ming Dynasty, he was shut up in the well by Liu Baowen. Liu Bowen said that the bridge had been repaired, the bridge was very old, the street lamps were not lit, and the old dragon king was released. However, he built the Moon Temple on this well and called it the "New North Bridge". Very clever. When the bridge is old, the old dragon king is always in the well. We will not discuss or verify the real existence of dragons. From a biological point of view, dragons can only be marine animals that exist in the sea, and their living range should not be too small, otherwise it is difficult to get enough food to ensure their survival.

All kinds of large animals in the world are threatened by human survival, and even humans are whaling. Why hasn't anyone found a "dragon" with real and reliable evidence so far? To sum up, as far as the current scientific and cultural research results are concerned, it is difficult to prove the existence of dragons. In fact, by symbolizing the supreme power of China, we can guess that it does not exist.

In ancient times, in order to ensure the "nature" and mystery of the supreme power, the choice of its symbol should be mysterious and unknown. There is also a saying that dragons are totems, combining different parts of many animals.

Even if you don't know the origin of Longjing lock, Longjing lock has something that ordinary people can't understand. First, it doesn't know the depth. Even if you throw a stone, you can't hear the echo, which is a bit scary. Moreover, I don't know the length of the two chains that hinder Longjing. Some people try to keep the chain in order, but it takes a lot of time and work. The chain seems to be flexible and can't find the source!
