Why did the top 32 soccer World Cup choose eight seed teams before grouping? What's the use?

The purpose of establishing the seed team is to avoid the premature encounter between the strong teams and the favourites.

The eight seed teams in the first file are the hosts and the top seven teams in FIFA. Since FIFA ranks every month, the choice of month is very subtle. For example, in the 20 14 World Cup, the seed team was selected according to the ranking in June of 20 13. Although Brazil is 11th, it is the host country. The first to seventh places are Spain, Germany, Argentina, Colombia, Belgium, Uruguay and Switzerland.

The FIFA World Cup, referred to as the "World Cup" for short, is a football match with the highest honor, the highest specification, the highest competitive level and the highest popularity in the world. Together with the Olympic Games, it is called the world's two top sports events, and even the world's largest sports event with influence and broadcast coverage exceeding the Olympic Games.
