Introduction to Li Bai: Li Bai, the great poet of the Tang Dynasty, came to Tianmen many times and left behind his well-known masterpiece "Looking at Tianmen Mountain". As the poem says: "The Tianmen interrupts the opening of the Chu River, and the clear water flows eastward from here, the green mountains on both sides of the bank face each other, and the solitary sails approach the sun." This best expresses the artistic conception of Tianmen Mountain.
