A river of clear water rolled eastward, and the change of the flowing image aroused the turbulent vortex. What ancient poem is it?

1, Tianmen interrupted the opening of the Chu River, and Higashi Shimizu flowed to this time. The green hills on both sides are neck and neck, and a boat meets leisurely from the horizon. -from the Tang Dynasty poet Li Bai's poem "Looking at Tianmen Mountain"

Explain in vernacular Chinese: Tianmen Mountain was suddenly cut off by the Yangtze River and divided into two mountains. The river rushed out of the crevasse, the mighty Yangtze River flowed eastward, was blocked by Tianmen Mountain, set off huge waves, whirled northward to the green hills on both sides, and appeared relatively continuously. I met a solitary boat from the horizon.

2, the old friend resigned from the West Yellow Crane Tower, and fireworks went down to Yangzhou in March. My friend's sail shadow faded away and disappeared at the end of the blue sky, only seeing the first line of the Yangtze River and heading for the distant horizon. —— Excerpted from Yellow Crane Tower, Li Bai's Farewell to Meng Haoran on the way to Yangzhou in the Tang Dynasty.

Interpretation of vernacular Chinese: My old friend waved to me frequently, bid farewell to the Yellow Crane Tower, and went on a long trip to Yangzhou on this bright March spring day. The lonely sail shadow of my friend faded away and disappeared at the end of the blue sky, only seeing a line of the Yangtze River, heading for the distant sky.

3. I came from Jiangxi, with Yunshan and terraces on the mountain. Mountains and rivers are connected, towers are opposite, and the sky is arranged. —— From the Yuan Dynasty: Zhao Yugui's "Breaking laurel trees and making Jiangxi come"

Interpretation of vernacular Chinese: The Yangtze River flows down from the west, and when it reaches Zhenjiang, the towering Jinshan suddenly rises abruptly in the river, and the terraces on the mountain are even more spectacular. The mountain is connected with the water, and the balcony is opposite, which is really arranged by God.

4. The Yangtze River is as white as practice, and Hu Aishan Mountain is as green as a lake. Fan Jiang is like an arrow, and the mountain spring thousands of feet flies like electricity. Sunset dew, new moon learning fan. The word Saihong comes like a line. -From the Yuan Dynasty: Zhou Deqing's "Sai Qiu Hong Xunyang as a Scene"
