《礼记·杂记上》
太子死，报丧时就说: 寡君的嫡子某某死。 大夫死了，在国内报丧时，如果是地位相当的人，应说: 某某不禄。 向士报丧，也说: 某某不禄。 
讣于士，亦曰： 吾子之外私寡大夫某不禄，使某实。 
When the prince died, he would say: "Our lord's legitimate son, a certain someone, has died." When a higher-ranking official died, he should say: "A certain someone was unfortunate." When reporting to a lower-ranking official, he should also say: "A certain someone was unfortunate."
