4A is also called Axel Jump Around. Axel jumping is one of the six jumping moves of figure skating, also known as the front outer point ice jump, first completed by Norway's Axel Paulson in 1882, and is the most difficult of the six jumps in the men's singles.

The reason why 4A is so difficult is because although 4A is counted as a four-way jump, A jump takes more than half a week, and actually turns four and a half weeks, compared with 3A, the highest point of 4A is 17cm higher, and the freezing point distance is 1.1m, in order to achieve these successful conditions, the skid speed needs to be increased by 10%, plus A jump is the only forward jump, when preparing to enter the rotation body, the center of gravity is on the outer blade of the ice knife, and when jumping, the ice knife may slide laterally. So let this jump become the most difficult action in the world. To date, no figure skater has successfully jumped out of the 4A in the competition.

After defending his title at the 2018 PyeongChang Winter Olympics, Yusei Yusuke targeted 4A, and he has been working hard for nearly 3 years.

In order to jump out of the 4A, Yu Yu was also injured this season. At that time, during a free skating training, when he finished jumping 4A and then connecting 4S, the ice knife was accidentally inserted in the ice, resulting in the inability to jump, and he injured his right foot. In the game of the 8th short program, Yu Yu's first action will be skipped, in fact, it is more or less related to this injury, he said that his body had a memory at that time, and consciously avoided possible dangers.

But even so, Yu Yu still insists on finishing the 4A in tomorrow's game. In this regard, he said: "For the challenge of the 4A action, there have been 3 years of ideas, especially in these two years, in quite a lot of training and practice, there are also such ideas. If everyone says that only I can do this, I want to complete it. ”
