During the Easter Holiday, our school hosted a 2-day, 1-night CS study tour for all S5 students. The study tour aims to strengthen students' historical, cultural and national knowledge. Through visiting different places in Shenzhen, such as Qianhai Shenzhen-Hong Kong Youth Innovation and Entrepreneur Hub, Shenzhen Museum, Nanshan Museum, The Reform and Opening-up History in Shenzhen and Nantou Ancient City, students gained a deeper understanding of Shenzhen’s history and culture, technological development, the opportunities for young entrepreneurs and the collaboration between Hong Kong and Shenzhen. This tour also help students have a better understanding of the close cooperation between Hong Kong and the Chinese Mainland from areas namely cultural preservation, economic development, technology innovation and start-up industries. It was an unforgettable and valuable experience for students and this tour further strengthened their sense of national identity.
