Appreciation: "Tianmen breaks the Chu River, and Higashi Shimizu flows here." These two lines overlook Tianmen Mountain and face each other across the river. The river passes through Tianmen Mountain, and the current is swift and swift, which shows the magnificent momentum of the Chu River rushing through Tianmen Mountain. The second sentence is about the river under Tianmen Mountain. In turn, it focuses on the binding force and reaction of Tianmen Mountain, which is facing Jiajiang, to the surging Chu River. Because the two mountains are opposite, when the vast Yangtze River flows through the narrow passage between the two mountains, it stirs up a whirlpool and forms a choppy spectacle.
