What is that overpass pillar in Shanghai with nine dragons engraved on it?

It is said that when the viaduct was being built, the ground pile of the middle pillar could not be driven in. The construction engineers tried many scientific methods, but to no avail. At this time, someone asked the "Zhen Zen" Master of the Jade Buddha Temple to help. The master came to the scene, looked at the feng shui of the place, and left without saying a word. Everyone was puzzled and hurriedly asked the mage for advice. The Master sighed: "If the secret is revealed, I may not live long." But in order to benefit all people, the Master can only reveal this century-old secret: "Now under your feet is the dragon head of our Shanghai Dragon Vein, and the Huangpu River is at the Yangtze River Dragon Spirit At the end of the day! Driving piles here is like breaking ground! If you want to drive down the bridge pillars, you must use dragon pillars to replace the dragon spirits. Starting tonight, you will carve the dragon pillars on the outside. I chanted sutras for seven days and asked the dragon spirit to transmigrate. However, if the divine position is changed, it will take away thirty years of my life, or it will kill me suddenly. It seems that I will die in seven days..."

Seven Later, when everything was ready, the pile driver easily drove the piles of the dragon-carved iron pillars into the rock formations at the bottom of the river. While the ground piles were being driven into the rock formation, it was said that red magma flowed out from below, possibly hurting the creatures underground. As expected, the abbot of the Temple of the Emerald Buddha passed away on the night of the seventh day.
