Comparison to “Action” in English: This is a crucial point for learners. In English, “action” can be very abstract. We say “We need to take action on this problem” or refer to a “course of action.” This is
not 动作 (dòngzuò). The Chinese equivalent for that abstract, planned “action” is
行动 (xíngdòng).
动作 (dòngzuò) is almost exclusively tied to the physical realm. You perform a
动作 with your body; you take
行动 with a plan.
