On March 6, 1945, Nee moved to Chongqing to oversee the factory there. There, he delivered a series of messages on Revelation 2 and 3 published as "The Orthodoxy of the Church" as well as messages on the Song of Songs. On September 9, 1945, the Japanese army surrendered in China, ending the Second Sino-Japanese War. In 1946, Peace Wang and Witness Lee began to work to restore the church in Shanghai as well as Nee's public ministry there. Nee purchased twelve bungalows at Kuliang to hold trainings for his co-workers in the Christian work. By April 1948, a revival was brought to the church in Shanghai, and Nee resumed his ministry there. When he returned, Nee handed his pharmaceutical factory over to the Christian work as an offering to God, influencing many others to hand over their possessions to the work. Within a short time, the church in Shanghai grew to over 1000 members.
