The study focuses on the WeChat usage and WeChat group activities by a group of ethnic Pumi youngsters.Adopting the methods of online ethnography and offline fieldwork to investigate their selfexpression and interaction,this study interprets how this new media platform gets embedded in their daily life and how they use it to construct multiple narrative.With this case,the essay offers a particular lens to look at WeChat as a new media technology;it posits that WeChat is an ego-involved process of writing and practicing culture;it gets integrated into people’s everyday life through a process that Roger Silverstone termed "double articulation." With WeChat,these users glide between life space in the reality and the virtual space of the network,interweave their individual conceptions with the beliefs of and on the ethnic groups to which they belong,and improve the pace as well as dimensions of interactions inside and outside their village.
