I just tried to share my understanding with u (and probably other readers here) on EDB's guideline re: adverse weather arrangement for schools / students, in response to yr statement "明明黑雨先停課的".
To be honest, despite Sat. being tagged as an arguably 'abnormal school day', it's rather amazing to get to learn the idea that a school organised event (with students' attendance) can deviate from / override EDB's guideline on adverse weather arrangement...
