Whether discussing the presentation of Chinese medicine at a health fair sponsored by a Silicon Valley corporation, or how the inclusion of a traditional Chinese medicine clinic authenticates the “California” appeal of an upscale residential neighborhood in Shanghai, Zhan emphasizes that unexpected encounters and interactions are not anomalies in the structure of Chinese medicine. Instead, they are constitutive of its irreducibly complex and open-ended worlds. Zhan proposes an ethnography of “worlding” as an analytic for engaging and illuminating emergent cultural processes such as those she describes. Rather than taking “cultural difference” as the starting point for anthropological inquiries, this analytic reveals how various terms of difference—for example, “traditional,” “Chinese,” and “medicine”—are invented, negotiated, and deployed translocally.Other-Worldlyis a theoretically innovative and ethnographically rich account of the worlding of Chinese medicine.
