This sentence means that there are many swift horses, but few people know them. The deeper meaning is that there are many talented people and good ministers who govern the country, but few people who have the vision to appreciate them.

This sentence comes from Han Yu's article Ma Shuo, one of the eight masters in the Tang and Song Dynasties. Although this article is about the way to know horses, it is actually about the monarch's principle of being a servant, and the situation of horses is used to compare the situation of talented people.

excerpt: There is Bole in the world, and then there is Maxima. There are many swift horses, but Bole is not. Therefore, although there is a famous horse, it is only humiliated by slaves, and it is not called a thousand miles to die in the trough.

Translation: There is Bole in the world, and then there will be a swift horse. There are often swift horses, but Bole doesn't often have them. Therefore, even if there is a swift horse, it can only be humiliated at the hands of servants and die in the stable side by side with ordinary horses. It cannot be known as a swift horse.

Extended information:

The first sentence of Ma Shuo is the major premise: "There is Bole in the world and then there is a swift horse". This proposition is illogical. Because there is a sense of decision, the knowledge and experience of Bole being kind to horses must be obtained from a large number of swift horses in society (or nature), and then gradually summarized.

So some people think that this sentence by Han Yu is putting the cart before the horse and idealistic. Judging from the principle of materialism, this sentence is wrong. Han Yu regards it as a language, but it is a thought-provoking epigram and a famous saying. Because there are too few people in the world who have the knowledge and skills of Bole. So the author points out the main idea in the front of the next article and pours out the infinite grievances of Maxima.

It is precisely because "Bole is rare" that many swift horses not only can't find a good herdsman, but are "only humiliated by slaves" and suffer from ignorant villains. These BMWs died in the ditch, which was unfortunate and had a tragic ending. Without treating these horses as swift horses, the death of swift horses is meaningless.

"Don't call it a thousand miles" means that there are no people who sympathize with them, let alone express regret, regret and regret for the death of Maxima. On the surface of the article, the author speaks thoroughly, but there are many bitterness and pains that have not been revealed. It seems to be unrestrained, but in fact it is rich in connotation.
