《礼记·奔丧》
奔齐衰以下亲属之丧，如果来不及在停殡待葬期间赶回，就要先到墓地，面朝西痛哭，尽情哀哭。在墓的东边脱去吉冠，戴上免，腰间系上麻带，然后就位，和主人一道痛哭跺脚，然后穿好衣服。
齐衰以下不及殡：先之墓，西面哭尽哀，免麻于东方，即位，与主人哭成踊，袭。
People who fail to make it back in time to mourn for the death of their relative below the rank of Qi Zhui, will first go to the graveyard, face west and cry their heart out. Then remove the auspicious hat and put on the mourning attire, tie a hemp belt around the waist. Then stand in line and wail with the host and beat the ground. And then get dressed.
