What's the story of Dragon Ball in Shanghai Town?

This is a superstitious event.

The story of the so-called "Dragon Column" is to the effect that when Shanghai was building the elevated Yan 'an Middle Road, one column could not be pressed down. After a mage was hired to do it, piling was successful. Finally, the pillar was covered with metal and carved with nine dragons. This column is called "Dragon Column". This "Dragon Column" is still here today. If you come to Shanghai for the first time and take a taxi through Yan 'an Road overpass, the driver's master will probably tell you the story of Dragon Column. Different drivers have different versions. It is said that there were many pillars on the bridge at that time, but the pile of this pillar could not be driven down. Experts have ruled out all geological factors and objective reasons, but they can't find a solution, which is very strange. In today's society, although few people engage in feudal superstition, we can still see many important activities, such as Gai Lou and bridge building. When building roads, people will be invited to "watch the feng shui" and "watch the time".

Of course, most of these things are not public, and sometimes it seems to have become a convention, but everyone keeps it secret. It is said that "Dragon Column" has become a "punching place", and many people go to have a look and see its elegance. It doesn't matter how credible its legend is. After all, it adds a little interesting talk to people's boring life.
