升平元年。敦煌沙門單道開至建康。不畏寒暑晝夜不臥。日行七百里。後入羅浮山石室坐亡。

In the first year of the Shengping era, the monk Shan Daokai of Dunhuang arrived in Jiankang. He feared neither cold nor heat and never lay down day or night, walking seven hundred li in a single day. Later, he entered a stone chamber on Mount Luofu and passed away while seated.
