New | For retired Hong Kong chemistry teacher, never too late to start a new business
Dora Yapp Lee has taught over 2,500 students in a career spanning 28 years

Dora Yapp Lee may have reached retirement age but she has no plan to stop working, having just set up her online education business.
“I always like teaching and I do not want to stop just because of my age,” Lee said in an interview with the South China Morning Post.
The former chemistry teacher in Hong Kong International School, where she taught for 28 years, retired last year.
“I do not think retirement from Hong Kong International School means the end of my teaching career. I wanted to continue my work and contribute my knowledge and experience with a different approach.”
She has taught over 2,500 students over nearly three decades and for those who took the AP Chemistry Exam, 85 per cent of her students received top scores of 5 compared with the global average of 10 per cent.
My mission is to teach all students. I do not only focus on the high achievers, but also reach out to those who are struggling and need help. No students are left behind
“AP Chemistry is equivalent to first-year university level chemistry. AP Scores of 5 are viewed favourably by US university admissions, and students often receive university credits,” Lee said.
