CONGRATULATIONS to those students who conducted research on The History of Wah Ying College, for the ''Education in Hongkong - Past and Present'' Exhibition, launched by the Hongkong Museum of History. The project is well-informed, lively and lucid. Not only is the handling of primary sources of a high standard, but also the careful study of the college's past done by high school students, have made this project as well as the whole exhibition, a real success.
