Why did the Paralympic Games raise four national flags?

It should be a tie between two people.

Zhangjiakou Division hosted the awarding ceremony of the 49th Winter Olympics and the 44th Paralympic Winter Games. Raising the national flag and playing the national anthem are the most solemn links in the award ceremony, behind which is the efforts of everyone in the flag-raising team. In their words, it is necessary to do things carefully in a "stupid" way to ensure the smooth and zero mistakes of the award ceremony. Although the award ceremony is held every night, the flag-raising team has been busy all day since 10 am. At most, they will hold ten awards ceremonies a day, which means raising 30 national flags. From flag-raising supervisor, flag administrator to flag-raiser, there are more than a dozen links, and each link must be checked repeatedly.
