At the opening ceremony last night, the Greek delegation from the birthplace of the Olympic movement was the first to enter, and the Italian delegation, the host country of the next Winter Olympic Games, came second from the bottom. The Chinese delegation, the host of the current Winter Olympic Games, finally entered, and the delegations of other countries and regions entered successively according to the simplified stroke order of Chinese characters.
Liu Yan, a distinguished expert of the Legal Affairs Department of the Beijing Organizing Committee for the Winter Olympics, said in an interview with the people's Daily that the order of entry of all delegations to the Olympic Games (Winter Olympics) is arranged according to the Olympic rules and Olympic traditions, which is generally decided by the host, but requires the consent of the International Olympic Committee. The order of admission to the Olympic Games used to be arranged in French or English alphabetical order, but in recent sessions, it has gradually been arranged according to some laws of the language and characters of the host country, such as Greek letters, Japanese fifty tone chart, Korean pronunciation, Chinese strokes and so on. The IOC has only one basic requirement in this link: the Greek delegation will always be the first to enter, so as to show respect for the birthplace of the Olympic Games. Moreover, according to the previous practice, the host is generally the last to enter the site.

In December 2019, the IOC Executive Committee adopted a decision in Lausanne, Switzerland, to adjust the order of delegation admission for the summer and Winter Olympic Games from the 2020 Tokyo Olympic Games. The national or regional delegations that have won the right to host the next Olympic Games will appear before the current host to highlight the special status of the host of the future Olympic Games. Therefore, at the opening ceremony of the Tokyo Olympic Games, the last three delegations to enter were the United States (2028 Los Angeles Olympic Games), France (2024 Paris Olympic Games) and Japan.
