HONG KONG - Twenty secondary and four university students will make an expedition to Mount Everest, the world's highest mountain. The group will study the environment while going mountain trekking. They will also visit local schools for a look at Tibetan culture. Vincent Fan Ka-chun, 15, says the training was hard, but that didn't stop him. 'I want to explore the world and learn more about how to conduct scientific research. I am also looking forward to meeting other students and local people.'
