Lau Sin Peng is a veteran Macao educator and historian of education. In the dual identity of "principal and historian", she has left two clear tracks across Macao's education world: a long teaching and school-leadership career at local schools such as the Commercial Night Secondary School, and a body of scholarship — led by A History of Macao Education — that leaves a systematic academic record of the city's Chinese-language education.
