What do you mean by taking the stairs?

Taking the stairs is taking the catwalk, like a model. One of the ways models walk the catwalk is to keep their shoulders still. Also, don't hunch over. Move your waist, but don't move your upper body. Modeling is also one of the main things. The catwalk is true, but the catwalk is more than just moving your legs. It drives its legs through the hip bone.

What should I pay attention to when taking the stairs?

The key to walking is to be steady. With a book on your head, you won't fall off when you walk. Moreover, don't sneak around, be friendly and coordinate with your background music and racket. Hand-foot coordination is also important. It's not that the higher you hold it, or the better your hands look. Mainly depends on the collocation of your clothes and music.
