An old photograph brought Tom Hemenway across the ocean to Kuliang, Fuzhou, where he reunited with his long-lost "Chinese cousin". A century ago, his ancestor, Dr Ruth Hemenway, dedicated her life to healing others in China. Now, guided by light and shadow, he walks the ancient trails to Kuliang and Liudu Hospital in Minqing, tracing a piece of Chinese memory gently preserved by the mountain breeze.
