To celecrate the 27th anniversary of the establishment of the Hong Kong Special Administrative Region (HKSAR), a People's Liberation Army (PLA) held an Open Day Activity, drawing significant attention from various organizations. Our students enthusiastically signed up for the event and toured the garrison camp, showcasing their immense passion for it. Following this activity, the students have gained a deeper understanding of the People's Liberation Army and the process of Hong Kong's return to the Motherland.
