We talk about pinching phenomena of Legendrian submanifolds in the unit sphere. In particular, utilizing the maximum principle, we obtain a new characterization of the Calabi torus in the unit sphere which is the minimal Calabi product Legendrian immersion of a point and the totally geodesic Legendrian sphere. This is based on joint works with Prof. Linlin Sun and Prof. Jiabin Yin.
