This book tells the story of J.O. Fraser, a missionary who went one hundred years ago to the Lisu tribespeople in the mountains of Yunnan, south-western China. When he went there were no believers amongst them, far less a church. Fraser learnt the power of witness to them and of persistent prayer in breaking through Satan’s strongholds. The Lisu today have the highest percentage, pro rata, of any minority people in China. A missionary must!
