In 1871, they moved to Cheefoo and built a house there called "Nan Lou". In 1873, John embarked on a taxing 600-mile missionary tour by foot, finding rest and sustenance at whatever establishments he could find along the way. In 1877, there was a famine in the province of Shantung (the "Great North China Famine"), and he played a pivotal role in raising funds, setting up a food distribution centre and organising a relief corps from quarters at Kao-Yai. Famine struck again in 1889, and Nevius's abilities were, once more, called upon.
