On our Staff Development Day, Mr. Cheung taught us how to use ChatGPT in teaching and administration. After that, Mr. Joe Yiu, who is a social worker, and Ms. Jasmine Tang, who works as an educational psychologist, talked to us about a serious topic. They taught us how to handle emergencies and why it's really important that we must report any cases of child abuse. It was a day full of learning for all of us.
