This sentence comes from "The Proud Fisherman" by Li Qingzhao of the Song Dynasty. The full text is as follows:
The sky is connected with the clouds and waves, and the morning mist is connected, and the stars are about to turn and a thousand sails are dancing. It's like the dream soul returns to the emperor's home, hears the words of heaven, and asks me diligently where I am going. My road is long and the sun is setting, and I am learning poems full of amazing words. Ninety thousand miles away, the wind is rising, the wind is still, and the boat is blowing away to the three mountains.
For the "cloud waves" in the previous sentence, Meng Haoran's poem has "Looking at the three mountains at sunset, the clouds and waves are vast in the sky", and Lu You's poem has "Like a rainbow, it is hard to escape the strong energy, how can I make a boat thousands of miles away from the clouds and waves?" "It all refers to Haitao. Thousands of miles of waves, raging straight up, and continuous morning fog, creating a grand artistic conception. This is to set off the complete atmosphere for the following sentence.
The "star river" in the last sentence refers to the Milky Way in the sky. Du Fu's poem has "the shadow of the galaxy in the Three Gorges is shaken", and Han Yu's poem has "the star river is all swimming, pitching and mesmerizing". Looking at the clouds and waves in the human world with the stars, I have the idea of ??transcending the world. To cross the stars, thousands of sails are racing, and the momentum is already extraordinary, but the author uses the word "dance", which changes the style of writing and makes it elegant. This kind of unrestrained "flying" is not only the vision of the predecessors, but also triggers Captivating the imagination of future generations, "Ninety Thousand Miles of Wind and Power" is extremely romantic
