Introduction to Guan Gong's Blocking Cao: After passing three pavilions, support the clouds and go straight up. Looking eastward among the scattered flowers and black flowers, there are two stones standing upright like people on the waist of the rising peak, facing each other up and down. The upper stone top is shaped like a helmet and tassel, like the majestic "Guan Gong", and the lower one is like "Cao Cao" wearing an official hat and court uniform, bowing to intercede. It is a famous landscape in Songgu Scenic Area.
