the teacher called me last friday about the date change. i think they made the right decision to postpone excursion. Usually March is good weather (not too hot/ humid), but this year is exception so i think it's acceptable. i also applied annual leave but we will go to the park if there the weather is fine. originally i wonder if all branches of cannan going on the same day, but it seems not all branches go on the same day. are you guys going to kam tin too?
