《周礼·秋官司寇·衔枚氏&司仪》
凡诸侯来朝见王，就前往畿疆迎接并行劳礼。到行郊劳礼、为宾客安排馆舍以及诸侯在庙中向王授玉的时候，都担任承摈。
凡诸侯入王，则逆劳于畿，及郊劳、眡馆、将币，为承而摈。
When the states of vassals came to pay homage to the lord, one would go to the border territory to greet them and perform the劳礼 (labor ritual). When performing the郊劳礼 (suburban labor ritual), arranging lodging for the guests, and when the vassals presented jade to the lord in the temple, one would assume the duties of the承摈 (usher).
