A symbol of the climate of fear and militarisation of everyday life during the Cold War, the air defence shelter left a lasting imprint on Chinese urban landscapes eliciting diverse local social, political and cultural responses. As a means of urban defence, shelters illustrate changing perceptions of foreign threat and its impact on everyday life during the Mao period and the Reform Era, from the rise and fall of the Sino-Soviet alliance to the Sino-American rapprochement. This bio uses the example of a specific type of shelter --the air defence tunnel-- to illustrate how perceptions of foreign threats shaped shelter construction, design and materiality.
As objects impacting both daily life and economic well-being of the rural population, agricultural tools were a central concern to farmers since the imperial era. During both the Mao era and the Reform era their technological improvement stood high on the political agenda. Orienting themselves to foreign models and native innovations these tools were expected to contribute to economic growth by raising agricultural productivity. This biography introduces a number of agricultural tools used during the Mao era that were shaped by social and political forces on both the central and the local level.
