1. Skiing originated and developed in Scandinavian countries. "Standing", "board", "snow" and "sliding" are the key elements of skiing. After long-term development, official skiing events include alpine skiing, Nordic skiing, freestyle skiing, biathlon skiing and snowboarding.

2. Biathlon actually belongs to the category of snow sports, but it is not only about snow, but combines the two different characteristics of cross-country skiing and shooting, so it requires athletes to have both the ability to turn from dynamic to static and the ability to turn from static.

3. Previous Winter Olympics were generally held in ski resorts with cold climate, often far away from big cities. Before Beijing, the only capital city that hosted the Winter Olympics was Oslo, Norway.

The 2022 Beijing Winter Olympic Games will be jointly held in Beijing and Zhangjiakou. This is the first time in the history of China to host the Winter Olympics.

Winter Olympics spirit:

The spirit of the Winter Olympics is the Olympic spirit, including "understanding, friendship, unity and fair competition".

The Olympic spirit was put forward by Pierre De Coubertin. In order to introduce a vibrant new education system to the motherland, Coubertin devoted himself to studying different contemporary education systems and the history of ancient Greece since he was a teenager.

He hopes that French youth can accept a new education system, that is, to strengthen moral cultivation and confidence, while exercising and cultivating courage and strong personality.

Through the investigation of the ancient Olympic Games, Coubertin realized that the ancient Greeks organized competitions not only to exercise their physique and show spectacular scenes, but also to educate people. He believes that sports competitions can temper people's will, cultivate people's character and exercise people at the same time.
