Li Bai In autumn, the trees on the Jingmen River are empty, and the canvas sails are hung by the autumn wind. This trip is not for the purpose of making a fool of myself, but because I love the famous mountains and enter the mountains. Yanzhong is the Yan River. The poet comes from famous mountains and rivers, but he went to Yiyue Yanzhong to appreciate the mountains and rivers, which shows the beauty of the mountains and rivers. Li Bai once wrote in the poem "Dream Wandering in Tianmu Mountain and Leave a Farewell", "I wanted to dream of Wuyue, and fly across the Jinghu Lake all night under the moonlight. The moonlight illuminated my shadow and sent me to Yanxi River." The meaning of the dream came to life on the paper. This trip is not for mackerel, but an allusion. Zhang Han, a native of Wu in the Western Jin Dynasty, thought of the delicious seabass and water shield in his hometown in the autumn wind, so he abandoned his official position and returned home. Li Bai used this allusion to emphasize his love for the scenery of the mountains in central Vietnam, and it was for the sake of majestic beauty. Go to Yanxi River for beautiful mountains and rivers. Wearing Xie Gong's clogs, climbing on the blue clouds, seeing the sun on the wall, hearing chickens in the air, and so on. Most of the poems in "Dream Traveling to Tianmu Mountain and Staying Farewell" describe the scenery of the Yan River, which is not exhausting to mention.
