Today, this strong Christian presence in the Lisu communities of China and beyond can be attributed at least in part to Isobel Kuhn and her idea to start what she called the "Rainy Season Bible School." This was a school borne of the fact that, in the heavily agricultural area where the Kuhns ministered, the rainy season disrupted all normal life. Isobel Kuhn formed a plan to hold classes during this agricultural down time, not only to preach the historic Christian Gospel but also to teach the Lisu the basics of the Christian faith. These classes were taught by Kuhn and others. From these classes, countless men who became evangelists and pastors took the Christian message to untold numbers of nationals and travelers throughout China.
