What feng shui is there in the Yangtze River estuary?

The geomantic omen of the Yangtze River estuary is that Shanghai belongs to the alluvial plain of the Yangtze River Delta, with complex stratigraphic conditions. Municipal Design Institute, Shanghai Urban Construction Design Institute, Shanghai Zhenghe Tunnel and other engineering companies involved in the project immediately mobilized technical forces to tackle key problems, but failed to pile up again and again. There is a story that has been told in Shanghai for a long time. A technical director of the project once rumored in the newspaper that the dragon decoration was installed purely for the beauty of the city. No one believed the explanation given by the engineering technical director. If it is purely to beautify the city, there are no fewer than hundreds of columns on the viaduct in Shanghai, all of which reveal the true colors of cement concrete. Only the next pillar at the junction of the North-South Elevated Road and the East-West Elevated Road is decorated with dragon patterns, which are gold patterns on a silver background. This is the hard evidence that the Shanghai government must leave behind.
