This is where the Yan’an Highway and the Nanbei Highway intersect and overlap; creating a crazy 5 layer highway intersection. What makes the intersection especially awesome is that each highway is lined with blue neon lights that come on at night.
There is a pillar that connects all 5 layers of the highway intersection featuring a Chinese dragon. The story is, there are some spirits (I heard from someone else that it was a “dragon lair”) under the area where they needed to build this intersection. So, they needed to build this dragon pillar on that spot in order not to mess with the feng shui (风水）
