Why it is on this list
A 340-page compilation, published under the banner of the author's own Hidden Dragon School of Neigong: what Danaos and McMillan wrote, interviews with a man the author presents as a third direct student of Chang, previously unpublished photographs and a letter from Chang to McMillan, and written instructions for level 1 and "level 2a" — one set given by that student, one passed on from a student of McMillan's. Recent and self-published, and the instructions are second-hand by the book's own account; read them beside the Safety article rather than instead of it.
