依神異經曰。東北方有鬼星石室。三百戶而共所。石傍題曰鬼門。門晝日不閉。至暮則有人語。有火青色（右此四驗出其御覽）。

According to the Shiyi jing (Classic of Divine Marvels): In the northeast, there is the ghost star stone chamber, where three hundred households share a place. Beside the stone is written: "Ghost Gate." The gate is not closed during the daytime; when evening comes, there are human voices and blue-colored fire (the above four verifications are taken from the Yulan).
