According to the relevant regulations of the International Olympic Committee, all participants do not need to pay any fees, on the contrary, the organizer will bear all the expenses of all participating athletes, coaches, officials, and work personnel during the Games, such as food, accommodation, transportation, etc., and if they apply, they will also pay the cost of round-trip air tickets for the delegations of the participating countries to China. For journalists, a certain amount of food and accommodation is charged, but the transportation cost is waived.

In order to give athletes from all over the world the opportunity to participate in the competition, the IOC also provides special funding for those countries that are at war or are in great difficulty. In particular, athletes in war countries can apply to the International Olympic Committee for special training funds, as long as their performance meets the requirements, they can participate, and this requirement is relatively low.
CCTV does not ask Wang Meng to explain for a reason, CCTV is the national media, not only the People of China pay attention, foreign media are also very concerned, although it is a sports competition, but also to be cautious, the national media in general even in the interpretation of their own country's games, but also fair and fair and moderately positive evaluation of opponents, in order to show the demeanor of a big country.
In the early network commentary, especially in the commentary on the fall of the South Korean team, Wang Meng's personality is relatively straightforward, and he wants to say it, saying what the Chinese speed skating industry wants to say but cannot say, although it is very happy, but it is caught by the Korean media. If CCTV occurs in this commentary, it may cause a series of unnecessary troubles.
CCTV generally does not accept, does not use controversial, there are negative people, although Wang Meng has achieved remarkable results, but there are also Lijiang fights and Qingdao infighting incidents, the impact at that time is very bad. CCTV has a better candidate. Short track as China's traditional advantage project, there are many commentators to choose from, commentary is not equivalent to the game, whether it is Dayang Yang or former national team coach Li Yan, it is not worse than Wang Meng's interpretation level, is a better choice. As a CCTV commentator, there must be a variety of rules and regulations, for people like Wang Meng, it is definitely not very fond of being constrained, and the explanation on the video platform is actually more suitable for Wang Mao, otherwise everyone will not see such an interesting side of the owner.
Why are there so fewer black athletes? There are many skill sports in the Winter Olympics, and black people are not very good at it, which is actually very normal, it is a genetic problem, just like there are few yellow or white people in track and field events that can win the championship. Short track speed skating and speed skating such as the pursuit of speed of the project, although the pursuit of faster results, but only in the straight line is to rely on physical strength to sprint, curves and other places rely more on skills to accelerate, the winter Olympics of various projects are still more inclined to skill rather than physical fitness.
Most of the Winter Olympics are ice and snow events, and most of the countries where there are more black people have a relatively hot environment, and black people usually have less exposure to ice and snow sports, and there will naturally be few high-level black athletes in ice and snow sports.
