"Guardians of the Great Wall" is an English audio drama developed for the multimodal learning resource "English Ranger: The Cultural Heritage Quest" (
https://www.edb.gov.hk/EnglishRanger). Through completing a series of missions centred on the Great Wall of China, students explore cultural heritage and develop a sense of national identity; use the four English language skills creatively and purposefully; and are encouraged to take responsibility for preserving cultural heritage and safeguarding national security.
In this episode, Sophie and Charlie explore the famous Badaling section of the Great Wall. As students join their adventure, they learn how the Great Wall was built in the past, why it was important for protection, and how modern technology such as drones helps to preserve it today.
