Andus established her academy in 1986, providing extra-curricular lessons to students aged 3 to 13 and covering phonics, creative writing, speech and bible lessons. In 26 years, as at 2024, her academy has served over 8000 students and conducted over 130 training workshops for parents, teachers and principals, with complementary topical seminars on parenthood, education planning and related matters. It also provides a realm for students, parents and teachers to all learn together.

About one third of the training was conducted in-school through lectures, parent briefing, in-class assessment, demonstrating the methods through short enhancement courses with students of the recipient schools, lesson planning and progress reviews - in sync with the needs of each school. The service has covered 100+ individual kindergartens and groups in Hong Kong, Shenzhen, Dongguan and Guangzhou. As supporting service, Andus distributes Jolly Phonics books and products.

Andus has also authored a set of phonics text book published by another publisher. From 2024, building on experience accumulated in 26 years, she will put more effort on training and enrichment of training materials to further promote this excellent teaching system.
