HONG KONG -- Having taught students for nearly two decades, Lau had never thought that his stable job could one day entail political risks until earlier this month, when the Hong Kong government deregistered a primary school teacher for discussing independence in his class.
The day after the news of the teacher became public, Lau, who had always created original material for his teenage students, spent a full day reviewing all of his notes and worksheets to ensure that no "sensitive topics" were included.
