The counterpoint of radical change and durable continuity which has characterised the Communist upheaval in China is nowhere so marked as in the ambivalent attitudes towards youth and age. Traditional China was a backward-looking civilisation, espousing a view of life and of history which esteemed past over present, age over youth, authority over innovation. The twentieth century has seen a definite, often violent, conflict between the generations, with the revolt of 1911, the May Fourth movement, and the Northern Expedition each expressing an aspect of the upsurge of youthful aspiration. The emergence of a Communist government has been marked by a drastic change in the official attitude, a new preoccupation with the future rather than the past, and sustained attention to the organisation of the youth of China, from which group will come the national leaders of the generation ahead.
