"课问" (kè wèn) is a Chinese term that refers to a traditional practice of asking questions in a class setting. In Engpsh, this practice is commonly referred to as "cold calpng" or "cold questioning."

The practice of cold calpng or cold questioning is typically used in classrooms or other educational settings as a way to encourage participation and engagement among students. It involves the instructor or teacher calpng on a student randomly or without warning to answer a question or participate in a discussion. This practice is intended to help students stay focused and attentive during class, as well as to encourage critical thinking and problem-solving skills.
