The granddaughter of the founding father of modern China, Dr Sun Yat-sen, gave her first lecture to primary school students at St Joseph's Anglo-Chinese School in Kowloon Bay recently. Lily Sun Sui-fong, who has spent more than a decade promoting Dr Sun's vision, spoke mainly about the life and thoughts of Dr Sun. Ms Sun chatted with the enthusiastic pupils after the lecture, fielding questions about her personal feelings towards Dr Sun, the historical events surrounding him, and the impact his Three Principles of the People (nationalism, democracy and the people's livelihood) had on the modern world. The lecture was aimed at deepening the students' impression of the 1911 revolution led by Dr Sun, an event mentioned in the Primary Five syllabus. 'It is nice for the boys to learn with an image in mind,' explained principal Yip Kai-kwan. 'Perhaps 50 years later, when they read about Dr Sun, they will remember today when they talked to Ms Sun.' Ms Sun was delighted with the occasion, and said she would offer to do more school talks in future. 'Education must start when they are young,' she said. 'Once they get older, prejudice is formed inside their minds. They will be like glasses full of water, with no more room for new ideas.' The lecture, arranged with the help of parents, marked the start of the school's 45th anniversary celebrations.
