Generally speaking, the concept of "death group" is divided into two categories: one is that most of the teams in the group are quite excellent, that is to say, two or three of the four teams belong to the world's top teams or are in excellent condition, and it is difficult for other teams to advance in this group;
The other is that perhaps the four teams are not the strongest, but the level is extremely close. Any team may be the first in the group or the bottom of the group. This is the real death group.
The losing match of the Olympic men's basketball team is the death group for the China team;
The unsuccessful Olympic Games will be held in late June, 202 1. The four hosts are Canadian (Victoria), Croatian (Split), Lithuanian (kaunas) and Serbian (Belgrade), which means they are divided into four divisions, and each division has two teams.
The specific competition system is as follows: three teams in each group play round robin, and the top two teams in each group enter the knockout stage. In the end, four teams from two groups in each division will be eliminated, and the team ranked first will qualify for the Tokyo Olympic Games. In other words, only four of the 24 teams can qualify for qualifying after the group stage and the regional stage.
