This paper applies Semantic Flow Dynamics (SFD) as an analytical framework to conduct a full methodological demonstration on Chinese civilization. Using a three-step structure — long-duration pattern scanning, Xin Model construction, and historical regression testing — the paper extracts 17 recurring behavioral patterns and 12 preconditions from over two thousand years of history, and constructs a working model (Xin Model) of Chinese civilization's Xin. The Xin Model comprises three components: Core Xin (there is and can only be one center under heaven), the Dynamic Mechanism (the position belongs to no one; whoever wins, takes it), and the Reproductive Mechanism (isomorphic organizations). Ten historical fracture points are used for regression testing; the Xin Model holds in all cases without structural revision. Five falsifiability conditions are specified as the model's death criteria. From this, a Pressure Accumulation Model is derived, describing Chinese civilization's historical rhythm: accumulation → sawing → fracture → civil war → hero → reconstruction → accumulation. The paper concludes by locating the present moment within this model.
