Make up a short story according to the poem "Looking at Tianmen Mountain".

On a sunny morning, poet Li Bai visited the beautiful Tianmen Mountain by boat. The boat swam all the way along the Chu River to Tianmen Mountain. Li Bai was stunned by the beautiful scenery in front of him. He looked up at the tall and majestic Tianmen Mountain, which looks like a Tianmen, facing each other on both sides of the Chu River. The spectacular mountain peaks guard the Chu River like two doormen. The surrounding trees are lush, and some are bent, like tour guides, welcoming guests who come to play; Some are like mushroom houses, sheltering tourists from the wind and rain; Birds are contending on the mountain, as if playing a sweet symphony. Please enter a composition topic to search for Chuhe River. Sometimes it flows quietly, sometimes it rushes, like a little girl playing the piano, and sometimes it is like a galloping wild horse. The turbulent water echoes in the mountains, deafening, and the mighty Chu River flows east, like a dragon flying up Tianmen Mountain, hovering under Tianmen Mountain. Li Bai took a boat to see the majestic, spectacular and magical Tianmen Mountain at sunset. I couldn't help improvising and created a great poem "Looking at Tianmen Mountain" that will be unforgettable for future generations.
