Yun lived in the time of the Cultural Revolution of China-no Bibles were to be found anywhere, because all of them had been burned and the families who owned them had been severely beaten or killed.

But through a dream and a miracle, God provided Yun with the Bible he needed.

Yun began to preach all over China. He was captured, but amazingly escaped, again and again. Thousands of people came to Christ, and together the Chinese Christians saw many miracles.
