宋神宗
Biographical sources agree that Zhang Boduan died in 1082 CE during the reign of Emperor Shenzong of Song, but disagree whether he was born in 983, 984, or 987. Zhang was honorifically called Ziyang Zhenren 紫陽真人, ranking him as a Taoist "zhenren" 真人 "real/true/authentic person; perfected/authentic person" (the "zhen" in the "Wuzhen pian"), one rank higher than a "xian" 仙 "transcendent; immortal" in the celestial hierarchy.
