can be confused at a glance. The most important difference is the competition picture. The snowboard jump and freestyle ski jump athletes compare their movements. The athletes stand in the starting area and fly out from the upturned slope in the jumping area to do somersaults and grab boards. Ski jumping and Nordic competitions compare the distance and posture in the air. Before the start, the athlete sits on the pole. After the start, the athlete uses the highly accumulated gravitational potential energy to jump into the air from the jumping point and fly a certain distance with the board in a V shape before landing.

. The snowboarding platform and the freestyle skiing platform will be held at the Shougang Ski Jumping platform in Shijingshan District, Beijing during the 2022 Beijing Winter Olympics. Each will produce a gold medal for men and women, a total of 4, here in the "big platform" The "big" is derived from its English name big air.

Ski jumping and Nordic biathlon will be in the 2022 Beijing Winter Olympics in Chongli Province. Centrally,Specific to the big jumping platform, there will be ski jumping men’s individual big jumping platform, ski jumping men’s group big jumping platform, nordic individual big jumping platform + 10km cross-country skiing, nordic group big jumping platform + 4x5km cross-country skiing4 A gold medal, the Nordic Olympics will only have men's competitions in the Winter Olympics. The platform jumping part is exactly the same as the ski jumping, except that the cross-country skiing competition is also carried out in addition to the platform jumping. The "big" in the "big platform" here is a relative concept. The big platform is larger than the standard platform, and the English name is large hill. The distance from the platform end to the standard point K of the Beijing Winter Olympics is 95 meters, and the distance from the platform end to the standard point K is 125 meters.

The two venues are also very different. The Shougang Ski Jump, also known as "Snow Feitian" or "Crystal Shoes", is built on the flat ground of Shougang , The shape design is inspired by Dunhuang, elegant and smart, with only one track; the National Ski Jumping Center is called "Xue Ruyi". There is also a big disc at the end, and there is a fault in the middle of the track. The big disc at the top is the starting area, and it also provides a unique perspective for the audience to see the athlete's starting state from behind without disturbing the athletes. This design concept makes "Snow Ruyi" the world's first starting area at the top. Set up a large building ski jumping site. The big disk at the bottom connects the two tracks and is the stop area for athletes after landing. The area here is equivalent to an international standard football field. The fault in the middle of the track is the break between the jumping point and the landing slope, so that the athletes can take off. The points fly out smoothly.

How to distinguish between athletes when they are not in the competition state, you can see snowboard . The snowboard jumpers wear snowboards, which are the easiest to be identified. Although the athletes of the other three events are all two snowboards, the length difference is obvious. The snowboards of the freestyle ski jumpers are short and most of them hold ski poles. The ski jumping or Nordic biathlete snowboard is very long, generally the height multiplied by 1.45, which is about 2.3 meters to 2.7 meters.
Look at the clothing again. Snowboard jumpers and freestyle ski jumpers wear ordinary ski suits, which are divided into tops and trousers. Ski jumpers and Nordic biathletes wear jumpsuits made of synthetic fiber materials, and there is no crease on the body. , And the clothing requirements are very strict.
In addition, these four projects have many differences. Although they are called the big jumping platform, they can be easily distinguished with a little understanding.
