What is the dragon column on Yan 'an Road viaduct?

This is a miracle story about the elevated road, which is almost a household name in Shanghai. It's been passed down for twenty years.

In the mid-1990s, the construction of elevated roads in Shanghai was in full swing. After the Inner Ring Road was completed and opened to traffic, Chengdu Road Elevated (North-South Elevated) and Yan 'an Road Elevated, which run through the urban area, were launched one after another, forming a "Shen" pattern running through Shanghai. Unexpectedly, the project reached the key intersection of the east, west, north and south viaduct, but the foundation pile as the main pillar could not be driven down.

The project was temporarily suspended. Somehow, there is a saying circulating quietly in private: Could it be the problem of Feng Shui and Long Mai? Do you want to invite Mr. Feng Shui to have a look? This statement was immediately opposed by engineering and technical experts. Therefore, the project headquarters invited all the technical elites involved in the project to gather here to gnaw hard bones. However, after the technical elites have shown their magical powers, they still can't hit the unmovable piles. Even if you barely score, it is far from meeting the design standards and engineering requirements.

As a result, the previous saying of praying to God and worshiping Buddha was quietly circulated on the construction site. You may delay, but time will not. It's better to have a move than not to have one. What's more, try it. Even if it doesn't work, it won't hurt much. Later, I hired a Shanghai mage. After the mage finished the ceremony, the stake was divided. It is said that because of enlightenment, the mage returned to the temple and died within a few days. The pillar was then surrounded by Bai Gang and decorated with dragon-shaped ornaments as a prayer to the gods who helped pile driving successfully.
