The first Model United Nations Conference of Southeast University is the first time that Southeast University has held such a conference. Model United Nations is an activity organized by officials and non-governmental organizations all over the world for young people. It imitates the United Nations and relevant international institutions, and holds meetings around international hot issues according to its operation mode and principles of procedure. Young students play diplomats from all over the world. In the form of United Nations meetings, through personal experiences such as expounding opinions, policy debates, voting, and making resolutions, I am familiar with the operation mode of the United Nations, understand the common problems faced by mankind, and think about my own role.
