【明報專訊】I am Dr Ching and I am an ophthalmologist (or simply put, an "eye doctor!"). I was born in the seventies and lived a rather ordinary grass-roots life. My father worked in a hardware factory and my mother was a garment worker. My grandparents, however, were well-educated people. They paid great attention to my studies so that I managed to make it into a prestigious school in Yuen Long: the N.T. Heung Yee Kuk Yuen Long District Secondary School. When I was in Form Five, my grades were exemplary. The school principal even wrote me a letter of recommendation so that I could enrol in the School of Medicine of the Chinese University of Hong Kong. To be frank, studying to become a doctor was not my childhood dream but, before I filled in the university admission form, I had witnessed two chilling traffic accidents. They changed my life forever because I was convinced that, no matter how rich, poor, problem-ridden or at peace you might be; only a doctor could save you when you were on the verge of death.
