For almost a year, the award-winning film-maker Sun Shuyun travelled alone along the Silk Road from China through Central Asia to India and back in the footsteps of a 7th Century Chinese monk.
Sun Shuyun joins Martha to tell her how her childhood in China's violent Cultural Revolution and divisions in her family led her to make this epic journey. 'Ten Thousand Miles Without a Cloud' by Sun Shuyun is published by Harper Collins; ISBN: 0007129645
