Su wrote two commentaries and criticized Zheng, but Zheng's version became the basis for later editions and scholarship (Boltz 1993:240). It was among the works carved into the 837 CE Kaicheng Stone Classics and was first printed from woodblocks between 932 and 953 CE (Boltz 1993:240). Three fragmentary manuscripts covering more than seven chapters were discovered in 1st-century Han tombs at Wuwei in Gansu in 1959. The first Western editions of the Book of Etiquette and Ceremonial were translations into French by Charles-Joseph de Harlez de Deulin in 1890 and Séraphin Couvreur in 1916. John Steele first translated the full text into English in 1917. Content After disparaging the repetitive and "unnecessary detail" in the text, John Steele described it as a "picture of the public and private life, education, family interests, and work-a-day religion of an average man in the China of 3,000 years ago" (Steele 1917:vii-viii).

When the washing is finished, they salute one another, and the personator goes up, but not the aide. Then the host fills the goblet and pledges the personator. Standing, facing north to the east of the eastern pillar, he sits down, laying down the cup, bows, the personator, to the west of the western pillar, facing north, and bowing in return. Then the host sits, offers of the wine, and drinks. When he has finished off the cup, he bows, the personator bowing in return. He then descends and washes the goblet, the personator descending and declining the honor. The host lays the cup in the basket, and making a suitable reply, finishes the washing and goes up, the personator going up also. Then the host fills the goblet, the personator bowing and receiving it. The host returns to his place and bows
