On 9 November, Choi Kai Yau College and Sacred Heart Canossian College jointly organized a countryside cleanup activity. Participants embraced the hard work, collecting discarded aluminum cans, plastic items, and other household waste from the mountains to help protect our natural environment. During this event, volunteers not only experienced the hardships of cleaning work but also learned about the knowledge of mountain ecosystems and environmental protection. This activity has brought every participant a physical challenge and raised their awareness of the importance of safeguarding our natural environment. The organizers hope that this activity will inspire more and more people to join the movement for environmental stewardship. Through collective efforts, we can maintain the cleanliness and beauty of natural spaces, preserving these precious natural resources for our community.
