This article studies Western (primarily Anglophone) representations of the Dan people (boat people) and the boat clusters on which they lived, relative to the mainland, in the island city of Guangzhou, focusing on 1842–1900. A change occurred over time, as the Dan went from being in close interaction with Westerners prior to the Opium Wars to being peripheral to Western interests and activities. This shift is evident in Western writings, and negative representations of the Dan came to dominate in the late nineteenth century. This mirrored changing sociospatial power relations between Westerners and the terrestrial Chinese, as Westerners increasingly gained access to the onshore city of Guangzhou itself, in part from the colonial island enclave of Shamian. Changing crosscultural interactions affected how the Chinese Others were perceived and ultimately how the Chinese whole was intertextually constructed in Western colonial discourse.
