一場鄉飲酒，開頭是兩個人都不肯先走。「主人拜迎賓於庠門之外，入，三揖而後至階，三讓而後升」——主人到鄉學門外迎賓，進門之後揖三次才走到台階，上台階又讓三次。禮書把這一段叫「致尊讓」：先把這個「讓」做足，後面才談喝酒。
誰謀這場酒
《儀禮·鄉飲酒禮》從擇人開始：「主人就先生而謀賓、介。」——主人去找鄉里的先生，商定賓和介的人選；然後戒賓、請賓。前一日陳設：兩壺酒放在房戶之間，玄酒在西；篚在禁南；洗放在阼階東南，水在洗東。到「羹定」，主人去速賓，賓與介、眾賓相隨而來。席次也先說清：賓、主人、介、眾賓的席「皆不屬焉」——彼此不相連。
進門之後是一串拜：主人與賓三揖到階，三讓而升；「拜至」——在階上再拜；然後主人取爵下堂洗爵，賓要跟著下來辭洗；洗畢升堂，「拜洗」。這一套動作，鄉飲酒義歸成三句：「三揖而後至階，三讓而後升，所以致尊讓也」；「盥洗揚觶，所以致潔也」；「拜至，拜洗，拜受，拜送，拜既，所以致敬也。」——尊讓、潔、敬，禮書說這是「君子之所以相接」。
獻、酢、酬
酒上來是三個動作，不是一輪乾杯。主人「實之賓之席前，西北面獻賓」，賓拜受、主人拜送——這是獻；賓下堂洗爵，回來「酢主人」——這是酢；主人再取觶「酬賓」——這是酬。三個動作各有拜、各有洗、各有升降。介受同一種禮，但「殺」：不拜洗、不告旨，程序減省。眾賓更簡：「升受，坐祭，立飲，不酢而降」——接了酒，坐著祭一下，站著喝掉，不回敬就下堂。同一場禮，賓、介、眾賓三種繁簡，等級就寫在這些差別裡。
所以這場的「敬」不是態度，是計數：拜幾次、洗幾次、誰先誰後、誰回敬誰不回敬，都有定式。義裡說得很直白：這一套做足，「君子尊讓則不爭，潔、敬則不慢」，於是「無暴亂之禍」。
坐與立
除了角色，還有一條年齡線。鄉飲酒義說：「六十者坐，五十者立侍，以聽政役，所以明尊長也。」——六十歲的人坐著，五十歲的人站著侍候、聽候差使，這是為了表明誰年長。又說按年齡加豆：「六十者三豆，七十者四豆，八十者五豆，九十者六豆，所以明養老也。」——豆數隨年齡遞增；這裡只記這個等差，具體擺什麼食物，禮書與日常飲食是兩回事，本文不列。
於是有兩條軸交叉：年齡定坐與立，角色定獻酬的次序與繁簡。賓最繁，介次之，眾賓最簡；而無論賓、介、眾賓，到了六十歲都坐，五十歲都立。禮書把這兩條軸分開寫，正是要它們同時生效。
樂與旅酬
中間有樂，不是背景音樂。「工入，升歌三終，主人獻之。笙入三終，主人獻之。間歌三終，合樂三終。工告樂備，遂出。」——歌三首、笙三首、間歌三首、合樂三首；每進一輪，主人都要向樂工獻酒。樂畢，「一人揚觶，乃立司正」——舉觶立司正，禮進入第二階段：賓酬主人，主人酬介，介酬眾賓，「少長以齒，終於沃洗者焉」——按年齡排下去，一直排到那個替人澆水洗爵的人。義的評語是「知其能弟長而無遺矣」：敬長，一個也不漏。
再往後：脫鞋、升坐、進羞，「無算爵，無算樂」——酒與樂都不計數；賓出，奏《陔》；次日賓穿著鄉服來拜賜，主人回拜，然後「息司正」。義把整場的效果收成五句：「貴賤明，隆殺辨，和樂而不流，弟長而無遺，安燕而不亂。」並記孔子的話：「吾觀於鄉，而知王道之易易也。」
別讀成風俗志
要分清這是儀式文本。它規定一場禮怎麼排，不記錄某個鄉多久辦一次、誰真的到場、辦得起辦不起。所以不能寫「當時人人如此」。參與者是鄉人、士、君子，賓、介、僎各有身分；這是一場有資格名單的禮，不是全鄉人的聚餐。
也不要把「六十者坐」推成當時的社會實況：這是禮書對座次的安排，不是對鄉里日常的統計。禮書要說的是「明尊長」「明養老」——用一場酒的座次，把年齡秩序擺出來給人看。
鄉飲酒禮的骨幹其實很短：迎、獻、酢、酬、樂、旅酬、賓出。它要的兩個字是「讓」與「長」：先在門口讓對方先走，再按年齡排座，最後連洗爵的人也排進次序裡。讀它要讀結構——誰先誰後、誰繁誰簡、誰坐誰立——而不是把它讀成一幅其樂融融的鄉間宴飲圖。

The host goes to the elder to choose the guest and the assistant (主人就先生而謀賔、介), invites them, and lays out the mats, two wine jars between the door and the room, the washing basin south-east of the eastern steps, water east of it. When the food is ready he fetches the guest; at the gate the host bows and the guest returns it, they bow to each other three times and reach the steps, yield three times, and go up; there are bows at arrival, at the washing, at receiving and at sending the cup. The host takes the cup, washes it, offers it to the guest at his mat, and the guest returns the courtesy with a cup (酢), after which the host pledges him with another vessel (酬). The assistant is treated to a reduced version, and the other guests simply receive, sacrifice sitting, drink standing, and go down without returning a cup. The musicians then enter: three songs, three pieces on the pipes, three alternating and three together, with wine offered to them. A cup is raised to instal the overseer; then guest pledges host, host pledges assistant, assistant pledges the other guests, 'in order of age, ending with the man who poured the washing water' (少長以齒，終於沃洗者). Shoes come off, seats are taken, and the drinking and music go on without count; when the guest leaves the pipe music sounds. The record notes the victim was a dog and that the cup was used for the formal offer, other vessels for the rest.
- 《礼记·乡饮酒义》（战国至汉初成书；维基文库本，未与点校本复核） — The essay on meaning. It opens with the three yields — 'meeting the guest outside the gate of the school, entering, three bows before the steps, three yields before ascending: this is to bring about deference' (三揖而後至階，三讓而後升，所以致尊讓也) — then washing the cup for purity and the five bows for respect. It gives the two social rules: 'those of sixty sit; those of fifty stand and serve to hear the duties: this makes clear who is senior' (六十者坐，五十者立侍，以聽政役，所以明尊長也), and the graded dishes for the aged — sixty gets three, seventy four, eighty five, ninety six — 'so that the old are provided for'. It reads the seating cosmologically (guest and host as heaven and earth, assistants as yin and yang, the three guests as the three lights, the three yields as the moon's three days), links the rite to teaching filial and fraternal conduct, and records Confucius: 'when I watched the village rite I knew how easy kingly government would be' (吾觀於鄉，而知王道之易易也). It ends with five results: high and low clear, full and reduced distinguished, harmony without dissolution, deference to elders with no one left out, ease without disorder.
