The following is an excerpt from The Heavenly Man: The Remarkable True Story of Chinese Christian Brother Yun by Paul Hattaway. Brother Yun recounted his testimony and ministry in China to Hattaway which Hattaway turned into the book.
Hattaway is the founder of Asia Harvest. The most recent edition of Themelios positively reviewed another book Hattaway wrote called Shandong: The Revival Province. For what it's worth, the review calls Hattaway "an authority on the history of the Chinese church" (among other things).
That said, there's some skepticism about the miracles in Brother Yun's life. The miracle that seems to receive the most criticism is the one I've excerpted below (along with Brother Yun's 74 day fast). At least from what I can tell, it seems many of the criticisms against Brother Yun can primarily be traced back to another Chinese Christian living in Germany named Titus Pan. Pan's pseudonym is Lin Mushe.
However, some people are skeptical about Pan too (e.g. here, here).
