British writer Zadie Smith's White Teeth tells the story of the three main families, the Jones, the Iqbals and the Chalfens in London. Smith doesn't describe London as simply a physical form of concrete space. Her city writing is embedded in British culture and parallelizes the experience of ethnic minority immigrants. Through the complicated description of London space in the second half of the 20th century, the novel displays the social state of multicultural coexistence and records the awareness change of yearning, disintegration and reconciliation for city dwellers, while they pursue their own space belonging.
