制度
制度 (zhìdù) means "system" or "institution" and refers to an established set of rules, regulations, or practices governing how something operates. It is commonly used in political, social, and organizational contexts, such as 审查制度 (censorship system) or 教育制度 (education system). The word carries a more formal and structural meaning than the general word 系统.
