《仪礼·燕礼》
如果有小国国君在，就要在卿前先进献他们，进献的礼仪与进献卿的相同。为他们在东阶西边设席。面朝北以东边为上位，是增加的席。
若有诸公，则先卿献之，如献卿之礼；席于阼阶西，北面东上，无加席。
If there is a monarch of a small country present, they must be presented before you. The etiquette for presentation is the same as that for presenting you. A seat is set for them on the west side of the eastern steps. Facing north with east as the upper seat, which is an additional seat.
