Fifty technology buffs visited research centres in Shenzhen to get a closer look at the mainland's latest developments in top-notch technologies. The secondary school students spent three days last week at technology institutes, research units and private companies that put innovative technology to commercial use. A visit to the Chinese Academy of Sciences' Shenzhen Institute of Advanced Technology helped the Hong Kong students learn about AI robot research, 3D graphic simulations and other innovative technology for manufacturing. They also caught a glimpse of how solar energy is applied in Shenzhen, and learned about the development of genetic engineering and 4D animation productions. The visit was organised by the Innovation and Technology Student Club. It was set up by the Chinese University and the Innovation and Technology Commission to get together young people interested in innovation. The students also had a chance to share their experience with 46 senior secondary students from Shenzhen, Zhuhai and Dongguan. Form Four student Chan Cheung-hin said the visit gave him in-depth knowledge of scientific topics to help with his classroom learning. 'The class schedule is so tight in Hong Kong that teachers cannot go into detail on these topics.'
