Why do ballet dancers stand on tiptoe?

"Ballet" originated in Italy and originated in France. "At first, it was a kind of dance performed by the masses for entertainment or in squares in Europe. In the process of development, it formed a strict standard and deconstructed form. In 1661, The French King Louis XIV ordered the establishment of the world's first star Candy dance school in Paris, establishing the five basic positions and seven hand positions of the bar, so that the bar has a complete set of movements and systems. These five basic feet are still in use today. The emergence of pointe dance makes the romantic ballet more light, elegant, transcendent and free from vulgarly, forming an elegant, poetic and aesthetic style.
