契丹好鬼而尊崇太阳，每月初一早晨，向东拜太阳，他们大聚会、处理国事，都以坐西面束为尊，四楼门屋都朝东。
契丹好鬼而贵日，每月朔旦，东向而拜日，其大会聚、视国事，皆以东向为尊，四楼门屋皆东向。
The Khitan revered ghosts, and held the sun in high regard. Every morning on the first of the month, they offered sacrifices to the sun. They held large meetings and handled state affairs, with the seat facing east as the most honoured position, and the doors and rooms of the four towers faced east.
