He is just 11 years old, but Primary 5 pupil Goh Bing Yao from Pei Chun Public School is being trained to become a service ambassador at Toa Payoh MRT station. Under SMRT's Adopt-a-Station programme, pupils get a chance to serve the community near their schools by volunteering as ambassadors. Their roles include greeting commuters, helping out with directions, and ensuring the elderly and people with disabilities are given priority to use the lifts. Twenty-one schools have joined the programme since it started two years ago. Besides ambassador duties, pupils get the chance to put up musical or martial arts shows, and art murals or exhibitions at stations.
