Why didn't Attila attack China?

Attila has a long way to go to attack China, and the counterattack is not worth the candle.

Nomads mainly fight by riding and shooting, and all the people are soldiers, coming and going like the wind. They are usually guerrilla in nature, and their strength may be slightly weak, but they have good endurance and are good at attacking from a long distance. This is precisely the reason why there is no way for western heavy knights, heavy infantry positional warfare and tank propulsion.

For example, the Huns can't capture the city, but they can't catch up with Attila, and they can bite you. As for why he didn't call back, the question is simple. It's a long way to go, and it's not worth the loss to call back.

Most of the nomadic invasions come from low productivity and lack of food and daily necessities. After the establishment of the empire, these problems were gradually solved. It is irrational to drive the army so far to retaliate.

Extended data:

In 4 18 AD, Attila, who was only 12 years old, was sent to the Roman court as one of the hostages in the peace treaty (when the first emperor of the Western Roman Empire, Emperor Honori, was in office). At the same time, the Hungarians also got Etius (the general who later commanded the Roman army and successfully resisted Attila's further westward advance) as a hostage exchange.

While in Rome, Attila received a good education in the court, and also learned about the traditional customs of the Romans and their luxurious lifestyle. The Romans hoped that this would enable him to bring Roman culture back to Hungarian territory and spread it, so as to increase the influence of Rome on neighboring nationalities. Hungarians, on the other hand, hope that by exchanging hostages, they can get more information inside Rome.

Attila tried to escape, but failed when she stayed in Rome. So he began to focus on the study of Rome's internal structure, and focused on Rome's domestic and foreign policies.

Sometimes, he even studies this information by secretly observing diplomatic meetings held by diplomats. It can be said that everything Attila learned at that time was of great help to his later rule of Hungarians and even the conquest of Rome.
