Athletes participating in the Winter Olympics not only have room and board, but also don't have to pay for round-trip air tickets. Of course, free is more than that. The accompanying coaches, international referees, BOCOG officials and other specially invited individuals are all on the list of gratis personnel. Such free treatment also has a premise: only after the approval of the organizing Committee can you enjoy such free treatment; Moreover, the number of events in each game is limited, not as many people as the coaching staff wants to bring. Some athletes come out to participate in the competition and will take their families to watch the competition. They can not only take part in competitions with themselves, but also browse places of interest in other countries in their spare time. Then, even if they live in the Olympic Village, they will not enjoy free treatment. For athletes, it is also necessary to pay attention to one point: the free accommodation mentioned here only means that the basic services in the Olympic Village are free. If you go out to stay in a hotel or go to other expensive places, you need to pay for it yourself.
