Liu Zhenying (), known as Brother Yun (, literally "Brother Cloud"), born 1958, is an exiled Chinese Christian house church leader, evangelist, and proponent of the Back To Jerusalem movement. Brother Yun was involved in the Christian house church networks in China during the 1980s and 90s. Accounts about his life and ministry are to be found in his autobiography, The Heavenly Man. Life in China Brother Yun's book tells both of great persecution, and a surprising series of miracles of deliverance very similar (though often even more 'extreme') to those found in the Bible. Despite a life of poverty in China, he since has spoken to thousands internationally with the Gospel message. Seen as a rebel among some Chinese for not joining the government-controlled Christian organization, he was imprisoned and tortured by the government authorities. His book reports that he became a highly wanted man across several provinces. He was finally arrested and sentenced to many years in prison. However, Brother Yun continued his ministry while in prison, with more claims of miraculous results. As a result, many prisoners and even prison officials are reported to have become born-again Christians. While he gained increasing favor from some officials, he also became a target of increased persecution by others. He was repeatedly beaten and became severely malnourished. While in prison, Brother Yun writes about undertaking a total fast without food or water for 74 days. After many years in prison, he escaped from Hangzhou from which it is reported that nobody had previously escaped. He described how he heard the voice of the Holy Spirit, telling him to simply walk out the heavily guarded prison gate. Despite the risk of being shot, he wrote later that he obeyed the voice, and walked straight through several closed prison doors in front of many prison guards, across the prison yard and finally out of the main gate. Brother Yun stated that it was as if he had become invisible to the guards who stared straight through him. Although many expressed doubts that such a thing could happen, some prison guards have lost their jobs for this 'embarrassing mishap.' It is claimed that the official investigation by the Chinese Government concluded that Brother Yun received no human help in his escape and therefore should remain free. These reports have been corroborated by prisoners who occupied the same prison cell as Brother Yun. He
