On April 15th, the “National Safety Education Exhibition” was opened at the Macao Returning Gifts Exhibition Hall. During the exhibition, our school organized the teachers and students of primary and secondary schools to visit the museum. The exhibition hall provides a comprehensive, systematic, intuitive and vivid display of national security through a variety of visual and vivid photo collections, film and television broadcasts, physical models, etc.  The exhibition gives teachers and students a wonderful lesson and a deeper understanding of the safety of our country to enhance their sense of responsibility for national security.
