In Chinese culture, where education (教育 jiàoyù) is highly valued and seen as the primary path to success, the act of 上课 (shàng kè) is a deeply ingrained daily ritual. It's more than just sitting in a room; it signifies a formal, structured transfer of knowledge that demands respect and discipline. A key cultural difference is the formality of starting a class. In China, when the teacher enters and says, “上课! (Shàng kè!)” (“Class is beginning!”), students will typically stand up in unison and greet the teacher with “老师好! (Lǎoshī hǎo!)” (“Hello, teacher!”). The teacher will respond, “同学们好! (Tóngxuémen hǎo!)” (“Hello, students!”), and then often, “请坐 (qǐng zuò)” (“Please sit”). This ritual, while varying in strictness, reinforces the hierarchical relationship and the cultural value of respecting teachers and the seriousness of the educational setting. This contrasts with the often more informal and casual start to classes in many Western countries.
上课 (shàng kè) is a high-frequency term used constantly in daily life.
