Where does "there is no swift horse in the world, and it is rare for people to have nine square heights" come from?

Jiufanggao: A good horse-lover in the Spring and Autumn Period. He once sought a swift horse for Qin Mugong.

1. The original source

Huang Tingjian

The day before yesterday, my friend assisted Cao, and I went to the embankment to recognize the blue robe.

the heart fluctuates with your water and spring, and the prosperity and harmony are high in jathyapple.

there is no swift horse in the world, and it is rare for people to be tall in nine directions.

when the wine boat came back from fishing nets, the flowers fell and the stream was as deep as a pole.

2. Translation

In those days, you, a noble and virtuous person, became a little official Cao. I saw you off, walked on the long beach, saw the green spring grass, and thought that you, too, were wearing a green robe, ranking next to me. Today, my mood is shaking with the spring waves of your water; Your interest, presumably, must follow the moon on the gate of Bing, and gradually rise. Hey, is there no maxima in this world? No, it's just that you can't find Jiufanggao who is good at horse-gazing in the crowd. There are boats to carry wine and nets to fish in my hometown, so let's go home. There are fallen flowers floating in front of our eyes in the stream where we used to play, and the water depth is just a pole.

3. A brief analysis

Crossing the Plain and Being pregnant with Li Zi was in Bingzhou, a seven-character poem written by Huang Tingjian, a poet in the Northern Song Dynasty. The poem fully reflects the author's unwillingness to be an official and urges Li to retire together. The first four sentences describe the scenery, which contains feelings, blends scenes and vivid images. The last four sentences are lyrical, and there is no bosom friend. It is better to go fishing. The word "in the world" is better because its meaning is connected and its pen can be opened and closed.
