'Fàng xué' literally combines 'fàng' (to release, let go) and 'xué' (school or study), meaning the official ending of the school day when students are released from classes. It refers specifically to the moment or process of dismissal—not just leaving, but the institutional conclusion of formal instruction. It’s commonly used in contexts involving children, schedules, and daily routines, such as pickup times, after-school activities, or parental coordination.

This term is neutral in register and widely used across mainland China, Taiwan, and other Mandarin-speaking regions. It appears frequently in spoken language and informal writing (e.g., text messages, school notices), but rarely in formal documents where terms like '课程结束' or '教学活动终止' might appear instead. Unlike 'xià kè' (to finish class), which can refer to any single lesson, 'fàng xué' always implies the end of the entire school day for students.
