Students and teachers from Huiji College in Hong Kong walked into the 15th China Air Show on the 15th to closely observe the latest achievements and technologies in the national aerospace and defense fields, and conducted science popularization and research activities with aerospace and defense as the theme. In this year's air show, Halls 1 to 7 are dedicated to the aerospace industry, showcasing advanced technologies and exhibits in the aerospace field. More than 20 Hong Kong students and teachers observed exhibits such as the Chang'e-6 probe, Magpie Bridge 2 satellite, and Long March 6C carrier rocket, watched flight performances on site, and also visited various fighter jets and weapons in the ground equipment display area. This study tour is organized by the Hong Kong Lixin Group in collaboration with the Chinese Society of Astronautics. Under the guidance of professional lecturers arranged by the Chinese Society of Astronautics, the students witnessed the development of national aerospace technology and defense technology. Many students took group photos next to the exhibits. This is my first time at an air show, and I am fortunate to have seen domestically produced new aerospace equipment exhibits up close, as well as advanced ground equipment. I feel very excited! Proud of the increasingly powerful technology of our motherland Liu Yuncheng, a student from Huiji College in Hong Kong, said. Previously, Hong Kong Lixin Group collaborated with the Chinese Academy of Astronautics to launch a series of online and offline activities. Among them, the "Innovation+Study Tour" brand launched aerospace themed products such as "Beidou Science Popularization Course", "1U CubeStar Science Popularization Course", and "Lunar Exploration VR Technology Science Popularization Course", which enhanced students' interest in science and cultivated their innovative thinking. It is reported that since last year, the "Innovation+Study Tour" brand has hosted over 400 study tours, with a total of nearly 80000 primary and secondary school students. We will further deepen our cooperation with the Chinese Society of Astronautics, continue to promote cultural exchanges among young people from Guangdong, Hong Kong, and Macao, enhance their patriotism, and contribute to the cultivation of a new generation of aerospace talents The relevant person in charge of Hong Kong Lixin Group said.
