Introduction to the Zhongjun Tent: In ancient times, it was a place for military use, later a place for praying, and now a place for leisure. It was named after King Wu stationed troops here when he attacked Qilu during the Spring and Autumn Period. The Zhongjun tent is surrounded by mountains on all sides and is flat in the middle. There are military recruitment stones and Chu Suchun at the bottom, Leigu Stone and Wuwang Terrace above, and Wuwang Spring in the west. There are also Sanqing Hall, Shengxian Spring, Xiuxian Cave and more than ten stone steles for blessings. It is surrounded by cliffs to the north and deep ravines to the south, with soaring red walls, towering ancient trees, flying pines and flying clouds, and fresh air. It was praised by the Qing Dynasty as "ten thousand folds of green pines, thousands of streams and the moon, and a meandering water surrounding the mountains." It is indeed an ideal place for people to relax and maintain health. There are three Pinus tabulaeformis trees and three Sanqing Halls in the central courtyard. The three Chinese Pinus tabulaeformis are named "Gulong Pine" and "Welcoming Guest Pine" respectively. "The Book of Songs·Song of Lu" once recorded that "the pine of Culai and the cypress of Xinfu" were recorded. The age of the tree and the beauty of its crown are truly rare.
