Tang Gaozu
The names Yuanliang (), Shenming (), and Quanming () are all associated with Tao Yuanming. Some of this confusion results from a naming taboo during the Tang dynasty, specifically that the characters for an emperor's name were impermissible to use either to write or even to casually pronounce. This taboo required the substitution of similar characters or words in order to avoid this prohibition. As the "High Founder" of the Tang dynasty (posthumously titled Emperor Gaozu of Tang) had the personal name Li Yuan, the "yuan" () character became taboo. So, since this was the same as the "yuan" in Yuanming, various authors substituted the synonymous "shen" () for "yuan"—both referring to "depths".
