Covariant phase space formalism plays a complementary role in addressing the quantum dynamics. In this talk, I will demonstrate its application in classical physics by establishing the criterion for both dynamic and thermodynamic stability of charges perfect fluid star. To this end, I will introduce the Lagrangian description of Einstein-Maxwell-charged fluid system and the concept of canonical energy, etc. I will end my talk with one by-product of our criterion and two outlooks.
