In volleyball, there are seven teams for men and six teams for women, and each team is divided into two groups. What is the schedule?

If you have enough time, you can adopt the group round robin system first, decide the top four in the group, enter the semi-final elimination stage, then the first group is the fourth group, the second group is the third group, and then decide the champion and runner-up. If time is tight, the men's team can draw lots, and one team will directly enter the semi-finals, and the other six teams will play one by one to decide the other three semi-finals seats. In the women's competition, two teams were bye-bye, the other four teams decided to enter the semi-finals, and then entered the semi-finals with the two teams who were bye-bye, thus deciding the third place in the championship.
