From juancun literature that emerged in the late 1970s, to homecoming literature in the 1980s, and through to the family history writing in the 2000s, Taiwan based second-generation mainlander writers have constituted a discourse of mainlander identity in the historical and cultural context of Taiwan. The topics that they address are often about how the mainlander group takes root in the island and how it becomes emotionally distant from Mainland China. In 2011, Chiang Hsiao-yun, a U.S. based writer who proclaimed herself as a “second-generation mainlander”, published Peach Blossom Well. This is the first work she produced after she had stopped writing for around 30 years. This work tells the story of a mainlander family’s homecoming trip, with the firstgeneration character Li Jinzhou being a Chinese intellectual with a non-military background. The novel emphasizes the different generations’ different opinions on China. This essay examines how Chiang’s migration experience is projected onto this story in terms of its interpretation of mainlander identity, and the ways in which the mainlander identity in this novel is distinct from those of other works by mainlander writers in Taiwan. It argues that they similarly demonstrate the mainlander characters’ disconnection to their original homeland. However, Chiang emphasizes that mainlander identity is distinct from Taiwanese identity, as the first- and second-generation characters are narrated as feeling alienated in Taiwan as a result of discrimination. She further positions the third- and fourth-generation mainlander characters in the framework of global mobility, seeking a broader context for interpreting mainlander identity.
