《礼记·曾子问》
礼毕，小宰走上堂，把放在几案上的束帛等祭品取下，埋在东西两阶之间。第三天，众主人、卿、大夫、士都来到殡宫，站在前天站的位置上，面向北。
小宰升举币。三日，众主人、卿、大夫、士，如初位，北面。
After the ceremony, the young attendant mounted the hall, took off the bundle of silk and other sacrificial offerings that were placed on the table, and buried them between the two flights of steps. On the third day, all masters, nobles, officers, and gentlemen came to the mourning palace, stood in the positions where they had stood the day before yesterday, facing north.
