The trajectory of gangcai during the 20th century can be broadly delineated into four distinct phases: (1) the Initial Stage (1920s to 1949); (2) the Growth Stage (1949 to the early 1970s); (3) the Flourishing Stage (early 1970s to the late 1980s); and (4) the Period of Decline (late 1980s to the late 1990s). This historical evolution spanned a succession of tumultuous geopolitical events, including the Sino-Japanese War, Second World War and the Japanese occupation of Hong Kong, the Chinese Civil War and the founding of the People's Republic of China, the Korean War, the Cultural Revolution in Mainland, the normalization of Sino-American diplomatic relations, and China’s Economic Reforms and Opening-up. Functioning as a vivid historical cross-section, gangcai stands as a poignant testament to these monumental epochs of transformation and change.
