As the Chinese Communist Party celebrates its 100th anniversary, Celia Hatton looks at how party slogans reveal the turbulent history of modern China. Throughout its existence, the party has used key slogans to communicate policy and mobilise the country's vast population. These messages reflect not just the ambitions of party leaders but also have a profound impact on the lives of millions. Using the BBC archive Celia examines the story behind eight key Communist Party slogans, from their early years as a guerrilla movement to the campaigns of China's current all-powerful leader Xi XInping.
