Pi Dingjun introduction: Pi Dingjun (1914-July 7, 1976), an outstanding general and strategist of the Chinese People's Liberation Army. During the War of Liberation, he led the first brigade of the first column of the Central Plains Military Region to break through the Central Plains, creating a miracle in world military history and making an immortal contribution to the liberation cause of the Chinese people. During the large-scale synthetic military exercise on July 7, 1976, Pi Dingjun took a plane to inspect the exercise area. Due to bad weather and low visibility, the plane unfortunately hit a mountain wall. The main body of the memorial garden cleverly uses a natural boulder that is nearly 3 meters high, 2.5 meters wide and weighs more than 20 tons. It fully reflects General Pi's power, courage and artistic beauty as a heroic general. .
