On 26th February, our Chemistry Panel Master Mr. Ching led a group of F.5 students to visit Dr. Vincent Ko, one of our distinguished old boys from the Class 1996. He is an Associate Professor of the Department of Chemistry in City University of Hong Kong. The purpose of our visit was to get advice for the Inter-school Chemistry Competition. Dr. Ko greeted us warmly. On top of giving us insightful advice, he also shared his study and research experience in his alma mater and university. It was no doubt a wonderful experience for both the hosting and visiting Xaverians.
