Regarding Hugh Hubbard, let me refer to a book which I quoted from in a thesis of mine on Watchman Nee - Paul A. Varg "Missionaries, Chinese and Diplomats" 1965
Varg describes the Fan Village Experiment undertaken by
Hugh Hubbard of the American Board Mission in north
In the community to which they came by invitation 80% of the men were illiterate, only one girl had received as much as a primary education, 92% of the schoolboys had trachoma; smallpox and TB were prevalent, the infant mortality rate was high, and there were unsanitary conditions.
During their time in Fan village they established a school. The people were taught hygiene. Wells were dug making it possible to water the newly planted cotton crops; co-operative marketing was organised; trees were planted. Christian instruction was requested and given.
Three years after they launched the project they found "real changes in lives, a new sense of the value of the personality, an appreciation of nature and nature's God, new motivation and a gradual development of Christian character".
