What kind of dance is pelvic dance?

The pelvis is the base of the spine. If you want to change your hunched posture, you should reduce the forward tilt of your pelvis. Whether the pelvis leans forward or not is controlled by the hip muscles. When relaxed, the pelvis leans forward, and when tense, the pelvis stands upright. Therefore, one of the keys to correct bad posture is to make hip muscles tense.
