Ms Lim and her mother, Julie, have visited schools and teachers' training colleges. She has also met the girl she has been sponsoring.
"Her name is Srey Chen, she's 10 years old, and she is in primary school in the Kampot province. It was so special to meet her and see first-hand how the trust is making a difference in the lives of the people in her community."
The Cambodia Charitable Trust now supports more than 6000 children, providing bikes, uniforms, stationery, books, toilets, clean water and teacher training. It supports 16 schools and two teacher-training colleges.
