The first sentence, "Tianmen breaks the Chu River", focuses on the majestic momentum of the Chu River. It gives people rich associations: Tianmen Mountain and Tianmen Mountain were originally a whole, blocking the turbulent river. Due to the impact of the surging waves of the Chu River, Tianmen was knocked open and interrupted, becoming two mountains.
The second sentence, "Higashi Shimizu flows to this back", in turn focuses on the binding force and reaction of Tianmen Mountain, which is confronted by Jiajiang, to the surging Chu River. Because two mountains are sandwiched in the middle, the vast Yangtze River flows through the narrow passage between the two mountains, causing a whirlpool and forming a choppy spectacle. If the last sentence is written by the mountain, then this sentence is the adventure of the mountain to the water potential. Some notebooks "return here" as "straight north", and the interpreter thought that the Yangtze River flowing eastward turned north in this area. This may be a fine explanation of the flow direction of the Yangtze River, but it is not a poem, nor can it show the momentum of Tianmen.
"The green hills on both sides of the strait are opposite, and the sails are alone." These two sentences are an inseparable whole. The first sentence describes the majestic appearance of the two mountains seen by Tianmen and Wang, while the second sentence reminds Wang of his foothold and shows the poet's dripping joy. The poet is not standing somewhere on the shore overlooking Tianmen Mountain, but his foothold is a "lone sail" coming from Japan.
The Lonely Sail Comes from the Sun vividly depicts the lonely sail riding the wind and waves, getting closer and closer to Tianmen Mountain, and the poet's joy at seeing the famous mountains and scenic spots. 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.
Because the last sentence is full of the poet's passion in the narrative, this poem highlights the poet's self-image while depicting the magnificent scenery of Tianmen Mountain.
