丧礼作为五礼中的”凶礼“之一，《周礼·春官·大宗伯》记载：“以凶礼哀邦国之忧：以丧礼哀死亡...”，丧礼是哀悼死亡的礼仪，是凶礼中最核心的部分。
丧礼中的丧服制度，依据血缘亲疏分为斩衰、齐衰、大功、小功、缌麻五个等级，称为“五服”。
Funeral is one of the Five Rites of ancient Chinese, The mourning attire system in funeral rites is divided into five levels based on the closeness of blood relations (of course, for male-line relatives as the main): Zhan Cui, Qi Cui, Da Gong, Xiao Gong, and Si Ma, collectively known as the "Five Mourning Degree".
