On 9 September, some of our students watched the live broadcast of the "Tiangong Class" Hong Kong and Macao Designated Session. Jointly organised by the Hong Kong Special Administrative Region (SAR) Government, the Macao SAR Government, and the China Manned Space Agency, the activity included an expert lecture, an in-orbit demonstration, and a student question-and-answer session. It was an invaluable opportunity for our students to observe interactive science experiments conducted by the Shenzhou-23 crew, and to know more about the unique environment of space and the allure of space science and technology.
