《礼记·奔丧》
来宾退出，主人拜送于门外，然后又返回原位。如果有的宾客来吊唁时迟到了，主人照样要表示拜谢，跺脚痛哭，送客出门，就像接待没有迟到的宾客那样。
宾出，主人拜送于门外，反位；若有宾后至者，拜之成踊，送宾如初。
After the visitors leave, the host will send them to the door, and then return to the original place. If some guests arrive late for the mourning, the host must still express gratitude, stamp his feet and cry, and send the guests away, just like receiving guests who have not been late.
