The eight-person and six-person groups in the Latin dance ranking competition are established to adapt to different competition sizes and number of participants.

In Latin dance competitions, eight-person groups and six-person groups refer to the number limits for participating teams. Eights require each team to consist of eight dancers, while Sixes require each team to consist of six dancers.

The setting of eight-person and six-person groups can make the competition more flexible and meet the needs of different sizes and regions, while also providing more opportunities for contestants to showcase their talents.

In short, the purpose of setting up eight-person and six-person groups in the Latin dance ranking competition is to adapt to different competition sizes and number of participants, making the competition more fair and interesting.
