The reason why Beijing can be the only Olympic city is that Beijing has successfully hosted the 2008 Beijing Summer Olympic Games and is hosting the Winter Olympic Games in 2022.
This is the only city in the world that has successfully hosted the Olympic Games for two seasons. Other cities that have hosted the Olympic Games have only hosted the summer Olympic Games or the Winter Olympic Games. No city other than Beijing has been able to host two kinds of Olympic Games.
Beijing is able to host the summer and Winter Olympic Games thanks to its unique geographical location.
Because Beijing has successfully hosted the summer Olympic Games in 2008, I won't introduce it here. I will mainly introduce the advantages of Beijing's successful hosting of the Winter Olympic Games.
Beijing's geographical location is around 40 degrees north latitude. Cities in this latitude are generally typical temperate monsoon climate areas. Cities in this latitude are mostly hot and rainy in summer, cold and dry in winter, with four distinct seasons and obvious cold and heat. Therefore, he can successfully host the Olympic Games in summer and winter.
Can the four seasons climate alone successfully host the two seasons Olympic Games? Certainly not. In addition, there must be unique geographical conditions.
There is a alpine skiing project in the Winter Olympic Games. This project requires the city to have a unique height difference of 800 to 1000 meters and a track distance of 3000 meters. The requirements of this project are very high. It happens that there is a drop of 900 meters in xiaohaituo mountain area in Yanqing District in the northwest of Beijing, and the length of more than 3000 meters just meets this condition.
Beijing has the above advantages, unique geographical environment and suitable climatic conditions, coupled with natural geographical advantages, making Beijing and its surrounding cities a "natural ice and snow field", and has a national ski jumping center "xueruyi", which is located in the arm bend of the mountains. It echoes with "ice jade ring" and ice and snow towns to witness this ice and snow feast.
Here is an open embrace, witnessing and looking forward to the players to show their skills.
