Why doesn't anyone in Beijing dare to lock Longjing? What's the mystery in this?

Because someone once tried to lock the big iron locks in Longjing, but after these people pulled these big iron locks, the inside of Longjing actually made a strange sound, and it was particularly fishy. So since then, few people dare to lock Longjing casually. Of course, there are many legends about Lock Longjing.

According to legend, after Zhu Yuanzhang established the Great Ming Dynasty, he suddenly had a dream when he slept at night. He dreamed that there was a dragon holding a dream for him, saying that he would come and drain all the water in Beijing. So Zhu Yuanzhang found his number one strategist, Liu Bowen, and told Liu Bowen his dream. Liu Bowen is a person who can pinch and calculate, and he is particularly capable. So Liu Bowen set a trap, fooled the dragon and finally caught it. Finally, Liu Bowen blocked the dragon in the sea eye, drilled three wells in the sea eye, and then pressed the dragon town in these three underground wells.

In order to prevent the dragon from escaping, Liu Bowen built three temples on the well to suppress the dragon. Later on, Liu Bowen, are you going to lock me up for life? In order to appease the dragon, Liu Bowen told the dragon that as long as this bridge becomes an old one, you can come out. The dragon sounds actually acceptable. It takes only a few decades for a bridge to become an old bridge, but who knows that Liu Bowen later changed the name of this bridge to Beixinqiao, which means that this bridge will never become an old bridge in this life, so this dragon will never get out.

Of course, this is actually just a legend, and the credibility is not particularly high. According to scientists' speculation, this Lock Longjing was built by ancient people to sort out groundwater, from which we can also see that the wisdom of ancient people is still relatively high. In the Ming dynasty, people knew to use some tools to dredge groundwater.
