In this talk, I will report our recent results on closed Reeb orbits, which include a complete characterization of Reeb flows on closed 3-manifolds with precisely two closed orbits, and also the existence of two symmetric closed Reeb orbits on dynamically convex contact (2n-1)-sphere with symmetry, especially I will explain the detailed proofs of these results. This talk is based on my joint work with Cristofaro-Gardiner, Hryniewicz and Hutchings, Abreu and Macarini.
