50 years ago, Mao Zedong launched the Cultural Revolution to rid the Communist Party of his rivals. He ended up destroying much of China's social fabric, calling on young, radical "Red Guards" to take party leaders to task for their embrace of bourgeois values and lack of revolutionary spirit. He ordered them to destroy the "four olds" - old ideas, customs, habits and culture. Religion was a prime target. Temples were ransacked and churches were destroyed. Religious leaders were sent to factories and farms for re-education through forced labour. Many of them died. Visibly, religion was all but wiped out. In recent years, however, there has been a strong religious revival. Some experts believe that by 2025 there will be more Christians in China than anywhere else in the world, despite the fact that religious freedom is still curtailed.

Ernie Rea explores the impact and legacy of the Cultural Revolution on religion in China with Martin Palmer, author and China expert; Isabel Hilton, Editor of the 'China Dialogue' website; and Laureen Leung, a Chinese Christian who was born in China in 1966 at the start of the Cultural Revolution and who now lives in the UK.
