Why watchman née was arrested part b:

“Nee received a 15-year sentence but was not released at the end of his term. His days were divided into three 8-hour segments: hard labor, “reeducation” and solitary confinement.

During his first 20 years in prison, he was allowed no communication so he knew nothing of what had happened to his wife. During his 20th year in prison he became sick, and his captors allowed him limited communication. He found out that his wife Charity had also been arrested and had died years earlier.

On June 1, 1972, Nee also died in prison after spending 20 years in chains for the Gospel.”
