Fifty years after the death of Isobel Kuhn, Christianity has been thriving in the Salween River valley where the Lisu live in China. Of the 18,000 Lisu who lived in Fugong, Yunnan, in 1950, 3,400 professed faith in Christ. As of 2007, it is estimated that 80-90 per cent of the 70,000 population make the same profession. In Yunnan, it is estimated that there are between 100,000-200,000 Lisu Christians in total. More than 75,000 Lisu Bibles have been legally printed in China following this explosive growth.
