A Cross-Country Running Race
A 5000-metre race, part of the Sports Festival of our school, was held by the school students’ union last Sunday.
150 participants from three grades were involved in the race. Among the most of the participants were students and teaching staff. The racing route started at the school gate and ended at the foot of the South Hill.
It turned out to be a great success. Not only does it build up our body but it also enriches our school life.
