It seems that the knockout round of the 2002 World Cup in Korea and Japan was not A 1.

In 2002, instead of A 1-B2, A 1-F2, C 1-H2, F 1-A2, H 1-C2, it was divided into the upper half. B 1-E2, D 1-G2, E 1-B2, G 1-D2 are divided into the lower half, that is to say, in the lottery stage, A, C, F and H are directly divided into the upper half, and B, D, E and G are divided into the lower half. In order to facilitate the schedule arrangement between Korea and Japan, the first half of the competition will be held in Japan and the second half will be held in South Korea. This competition system has also brought some disadvantages. For example, Brazil and Turkey, both in Group C, met in the semi-final. The general competition system will not arrange this. Only after the two teams meet in the group stage will they meet again in the final or the third or fourth final.
