On February 16th, 62 parents and students participated in a Local Guided Tour under the North District Signature Project Scheme organised by the North District Office. That day we joined a guided tour led by four experienced geological park guides to Kat O and Ap Chau. In addition to learning about local geomorphology and other geological knowledge, the tour guides also explained the culture and history of Kat O and the Ap Chau to us. Students could also make tea pots by themselves. This journey made us realize that "Traveling thousands of miles is better than reading thousands of books." We sincerely thank the staff and guides of the North District Office for their thoughtful arrangement and explanation.
