The Chinese word 按部就班 is a four-character idiom formed by combining individual characters with specific meanings: 按 means "according to", 部 means "section", 就 means "to take up", and 班 means "order". Historically derived from a Jin Dynasty poem about literary composition, it literally translates to "follow the sections and take up the order", conveying through this structure the idea of proceeding systematically step-by-step according to a established sequence or plan.
