With the special support from the Chinese Government, Hong Kong has earned an invaluable opportunity to appreciate the breakthrough of China’s space technology: we can catch a glimpse of the lunar soil samples collected by the Chang’e-5 spacecraft in China in December 2020. With an attempt for students to broaden their horizons and heighten their interest in aerospace engineering, a visit to the exhibition “In the Call of the Times: A Thematic Exhibition of Chinese Scientists over 100 Years” was arranged for students on July 5, 2021.
