If the level of female players is relatively poor, the second scheme can be adopted: divide them into two groups, with 3 men and 6 women in each group, 4 mixed doubles (including high-level male players and one event), 1 women's doubles, with 5 wins and 3 losses in each game.
Groups can draw lots (male and female players draw lots separately: three men in group A and three men in group B; Female group a and group b each have 6 signatures) and direct distribution. In order to enhance the antagonism and appreciation of the competition, if you are familiar with the level of each player, it is recommended to adopt direct distribution.
