课本注《叔向贺贫》“宣子拜稽首焉”一句的“稽首”是:“顿首,把头叩到地上”。这个注释是不够确切的。稽首、顿首、空首,都是我国古代叩头的礼节,然而叩头的程度不同。《周礼》中有:“一曰稽首,二曰顿首,三曰空首”之说。“宣子拜稽首焉”,这里的稽首,是当时九拜中最恭敬的一种礼节,要跪下,拱手至地,头也要至地,并且还要等会儿抬起头来。顿首,是平辈相尊的一种礼节,叩头触地即可抬起来。如南梁人丘迟的《与陈伯之书》 The note in the textbook Note “Uncle to the Poor” “Xuanzi Baiji first” is: “Don’t be the first person and put your head to the ground.” This comment is not exact enough. Jishou, Dangshou, and Kongshou are the etiquettes of ancient Shantou in China. However, the degree of Shantou is different. “Zhou Li” includes the following: “Once the first ruler, the second ruler, the first ruler”. “Xuan Zi’s first visit to Baji” was the most respectful courtesy of the nine worships at the time. He must kneel down, hand his head to the ground, and head to the ground. He must also raise his head and wait a moment. The first meal is a courtesy honoring the flats, and the skull can be lifted when it touches the ground. For example, “The book with Chen Bozhi” written by Nan Liang Ren Qiu
