First of all, judging from the lottery, randomness is unscientific. It should be the principle of grading lottery. For example, the number 1-4 in the world is the seed and the first gear, 5-8 is the second gear, 9- 12 is the third gear, and 13- 16 is the fourth gear. It is easier to avoid being in the same country if each group contains a pair of players with 1-4 files.
Secondly, in the competition system, we can learn from the Tang Oil Cup. The top three teams qualify, the first team directly enters the quarter-finals, and the second and third teams compete for another quarter-finals.
The knockout round is:
The eighth final:
( 1)B2-C3
(2)A2-D3
⑶D2-A3
⑷C2-B3
Quarter-finals:
(5)A 1-( 1) winner
(6)B 1-(2) winner
(7)C 1-(3) Winner
(8)D 1-(4) Winner
Semifinal:
(9)(5) Winner -(6) Winner
(10)(7) Winner -(8) Winner
3 and 4 finalists
(1 1)(9) negative -( 10) negative
final
(12)(9) Winner -( 10) Winner
