Guessing is not a shot in the dark, but telling a certain truth. This is the fun and learning of guessing. Consider this:

This is a leisurely poem full of wild interest, indicating that there are guests visiting. Living in the countryside, especially the elderly, is nothing more than six kinds of animals, and ancient poems really reflect six kinds of animals that people like or even rely on (unlike modern people, snakes, chameleons and so on are all pets). There are generally only two kinds of animals that can accompany guests during the day: horses and dogs. But only the horse is lonely at night, and the dog barks at night.

Then think about it in a sense. Fang Feiri is when the sun shines high, which means noon, noon fire and noon horse. The silky sideburns and long silky manes of horses are the most distinctive of the six animals. So it is also a horse.
