《礼记·奔丧》
奔丧者于是戴上帽子，回到家门口，从门的左边进去，面向北而哭，尽哀为止；然后戴上免，袒露左臂，跺脚痛哭；然后在昨阶之东就位，主人为之拜宾，而奔丧者跺脚痛哭。来吊的宾客退出，主人拜谢送出门外。
遂冠归，入门左，北面哭尽哀，免袒成踊，东即位，拜宾成踊，宾出，主人拜送。
Then the mourner puts on the hat and returns to the gate of the house, enters the door from the left, faces north and cries to express grief, then puts on mourning attire, exposes the left arm, and beats the ground with the feet and wails; then takes place in the east of the steps, the host will greet the mourner, and the mourner will beat the ground and wail. The mourner will withdraw after greeting the guest and the host will express gratitude and see the guest out the door.
