DOGA co-organised the 155th Anniversary Concerts together with the DGS School Council and the DGS PTA on the 10th and 11th July 2015. We published a 20-page concert programme in support of the event. With courtesy of Vanessa Leung, our chair of the DOGA Art Club, we arranged for the photograph-shooting and created the digital artwork from it. To view the concert programme, please see click here (p.1-6)(p.7-12).
