The Retreat Day was held on the first day of school after the holiday. Both teachers and students have not met each other for a long time. This event can help teachers and students to know the importance of mental wellness, to strengthen the relationship, to set goals for the second term, and to prepare for the challenges in the future. Under the pandemic, the event was held in the form of online meeting on Moxtra. Students and teachers were having so much fun in the event.
