How do five groups of tug-of-war make rules?

Suppose that groups A, B, C, D and E draw lots to play the game, two groups play first, and one group remains.

1, assuming a-b, c-d.

A and c won. Go to the next round.

2、A——C、B——D

The conclusion that A and B win A > C & gtB& gt；; D. Enter the next round

3. Choose a group from C and B and compare it with E. If E wins, it will be compared with the top, and if E loses, it will be compared with the bottom.

Individuals can refer to it.
