In terms of formation, I really can't think of any formation other than square. Square is better. Otherwise, a heart-shaped one will do. I've seen heart-shaped ones at school before, not bad! Few people are easy to put out. As for the slogan, I found it online. You can learn from Class Two, Class Four, Grade Two. It's amazing. Strive for the first place and bravely win the championship! Sail at the helm and fight bravely. Look at my Class Four. It's magnificent.
