"Xiao's rules, Cao's follow" comes from the "House of Chancellor Cao" in Records of the Grand Historian. In the early years of the Western Han Dynasty, when Xiao He served as chancellor, he established a complete set of laws and regulations. After his successor Cao Can took office, he believed that these institutions were already very complete, so he followed Xiao He's established rules entirely without making changes, allowing the people to recuperate and recover. The idiom literally refers to the rules set by Xiao He being followed by Cao Can, and its deeper meaning is that a successor fully inherits the reasonable systems or practices of a predecessor and does not easily change them. It is often used in political, managerial, or workplace contexts to emphasize policy continuity and stability and to avoid frequent changes in policy. In terms of emotional coloring, the idiom is mostly neutral with a positive leaning, affirming the wisdom of inheritance and preservation, but it sometimes also implies a lack of innovation and a tendency to follow old ways, so it needs to be judged according to context. In terms of cultural background, it reflects the Huang-Lao idea of "governing by non-interference" and the dialectical thinking in Chinese tradition regarding "preserving what has been established" and "bringing about change."
