How is the volleyball system of Beijing Olympic Games supervised?

According to the original regulations, 12 teams participating in the Olympic volleyball group match are divided into group A and group B for single-cycle elimination, and the top four teams will advance to the cross match. FIVB decides to draw lots for the second and third place in each group in the quarter-finals, that is, the rules of the first place in Group A to the fourth place in Group B and the first place in Group B to the fourth place in Group A remain unchanged, but who plays between the second and third places in the two groups depends on the lottery results.

Look at the points, China's points are enough to qualify ~ so promotion.
