Guan Yu’s messages were received by mediums through spirit writing, later called Fuji (planchette writing) (), since the late 17th century. “By the mid-Qianlong period (1736–96) the number of ‘sacred edicts’ issued by Guandi ordering people to do good and help those in need became increasingly frequent.” In the 19th century, Guandi’s messages received through spirit writing assumed a millennialist character. Dates were announced for the end of the world, followed by messages indicating that Guandi had “prevented the apocalypse” and was indeed “the savior of endtimes.” In 1866, the Ten Completions Society (Shiquanhui 十全會) was established to propagate the messages of Guandi and promote the charitable work his spirit had ordered to perform. The tradition of Guandi spirit writing continued in Chinese folk Religion well into the 20th century.
