Introduction to Dragon Vein Ridge: The origin of the name "Long Vein Ridge" is because it is said that when excavating the Rouge River, Liu Bowen discovered that there was actually a dragon vein here. The tip of the shovel stuck in the ground. After a few days of this, the hills on both sides of the river were dyed red with dragon's blood. The dragon's veins were broken, and the river-opening project went smoothly.
