Translate the ancient poem "Looking at Tianmen Mountain" into a 300-word article.

The majestic Tianmen Mountain was split by the Yangtze River, opening a passage for the Yangtze River. Does Tianmen Mountain lock the river horizontally and leave a passage for the Chu River? Or did the giant stream rush out of a heavenly gate? The turbulent river ran from west to east and hit Tianmen with thunderous force, so the mountain was cut off from water. Ah! What a magnificent picture! How amazing! The clear river flows eastward here, and then flows circuitously to the north, surging. The general flow direction of the Yangtze River is from west to east, but when it reaches Tianmen Mountain, the river suddenly flows northward. Because of the two mountains sandwiched between them, the river narrows, which makes the mighty river surge and forms a choppy spectacle. Although the river can wash away the mountains, the mountains have choked the river and the river has to turn around. The river is like a green belt, flowing slowly and pleasing to the eye. The green hills on both sides of the river are relatively towering, standing there like giants, guarding the peace of Tianmen Mountain. Tianmen Mountain forms two symmetrical peaks, one on each bank, and the Yangtze River flows in the middle, forming a natural landscape painting. The poet stood on the boat and looked into the distance, unaware that the boat was sailing. With the constant change of distance, he only felt that Tianmen Mountain seemed to come out from the river bank. At this time, he could not help screaming and cheering when he saw such a beautiful scene. A lonely sail comes from the sun. This sentence suddenly pulls the camera away, and the eyes are suddenly open and boundless. Looking ahead, the poet saw that the Yangtze River was vast and confused. At the junction of water and sky, there is a lonely sail with a sun in the background. We are no strangers to such a scene, as if we saw a painting or a photographic work, vividly depicting the scene of sailing alone and getting closer and closer to Tianmen Mountain, and enjoying the beautiful scenery of the famous mountain with the poet. It seems to contain such a subtext: the majestic and steep Tianmen Mountain, a long-distance traveler riding a solitary sail, finally met you today!
