On February 26, 2024, a warm current rose in the cold winter. The Hong Kong Tianyi Charity Foundation, in collaboration with the Education Bureau of the Hong Kong Special Administrative Region, deepened students' understanding of the important history of the country to cooperate with the Hong Kong government's patriotic education and learning activities. The "Light and Shadow on Campus" series of activities aimed at cultivating students' patriotism and increasing their recognition of national identity. A new way to promote patriotic education through watching movies is to send the patriotic and Hong Kong themed film "Umbilical Cord" to the University of Hong Kong.
