This year we chose a 2-day trip of Route 6, Study Tour on Economic Development of Nansha & Qianhai, 16th-17th Nov 2023. This is our second mainland study tour (MST) since the implementation of the CS curriculum. We visited Qianhai and Nansha to learn more about the economic development and conservation of both tangible and intangible cultural heritage in Guangzhou in the Greater Bay Area (GBA). 100 students (and 11 teachers) excitedly looked forward to having a pleasant trip. All eight class teachers were enlisted and CS teachers surely joined this trip.
