The educational chief said schools should not be "overreacted" on national education, citing the incident of St. Francis Xavier's School in Tsuen Wan that suspended 14 students from school for three days over "disrespectful behaviours" towards the national anthem and the flag-raising ceremony. In a radio programme on Sunday, Secretary for Education Christine Choi Yuk-lin said that national education aimed to cultivate the young generation with patriotism, and the government would support schools with better professionalism in national education. "The disciplines are not meant to punish students but help them better understand the national anthem and flag," Choi said. "However, there is room for improvement when schools enforce the rules," she said, noting the involved St. Francis Xavier's School has launched an investigation. Choi added the education authority would strengthen the conduct guidelines and training for national security education on teachers.
