《水经注·卷一》
城池已经荒废，只有一片空荡荡的荒地。但这里还住着二十余家姓释的优婆塞，他们是旧时净饭王的后裔，但分为四个种姓，住在这座荒城中。因为他们是优婆塞，所以重视修行，还有些古风。
城池荒秽，惟有空处，有优婆塞姓释，可二十余家，是昔净王之苗裔，故为四姓，住在故城中，为优婆塞，故尚精进，犹有古风。
The city is deserted, leaving only a desolate wasteland. But more than twenty lay Buddhists of the Sakya clan live here. They are the descendants of King Jingfan of ancient times, but they are divided into four castes and live in this abandoned city. Since they are lay Buddhists, they pay attention to practices and have some old-fashioned customs.
