According to the regulations, it is understandable that the accommodation expenses of domestic athletes participating in the Olympic Games should be borne by their own countries. After all, they want to do their own thing, but many small and poor countries in the world really can't afford the money. However, as a world-wide sports event, it is a pity that athletes from some countries can't participate because they can't afford the money. Since the Sydney Olympic Games in 2000, the organizers began to provide free accommodation for athletes from all over the world. Since then, it has become a routine and an unwritten rule. I think it's ridiculous that a country gave up taking part in the Olympic Games because it didn't give free accommodation. Can't a country afford the accommodation and meals for several athletes during the competition? Is the Olympic accommodation expensive? Why should a country train Olympic athletes when it can't afford the food and accommodation for athletes? Accommodation during the Olympic Games can be charged at the preferential price of the usual ordinary price, and no price increase is allowed. The host country can't just give foreign athletes free enjoyment with people's taxes!
