Tungning, one of the most isolated towns in all Manchuria, is four hundred miles east of Harbin. To get there, I went by rail to the border town Progranichnaya, where the Chinese Eastern Railway enters eastern Russia (Siberia), then traveled sixty miles south through wild mountains on the Manchuria-Siberia border, a journey of one day by bus or two days by Russian wagon.[…] At Tungning we found a well-to-do Christian who was the leading carpenter of the town. He was known by all as a believer. Although the population of Tungning was large (40,000), no one knew of any missionary or other Christian worker having ever been there. They did know of some Korean Christians in a village nearby. Tungning was a real frontier town, and the only one in all China where we had seen no heathen temple.]
