《仪礼·聘礼》
在馈赠牛羊豕十天后送来粮米。宰夫开始送成双的雉、雁等，每天送上的雉、雁的数目同牛羊豕的数目相同。
既致饔，旬而稍，宰夫始归乘禽，日如其饔饩之数。
Ten days after they had presented cattle, sheep, and pigs, they would send over food grains. The slaughterer would then begin to send pairs of pheasants and geese, and the number of pheasants and geese sent each day was the same as the number of cattle, sheep, and pigs.
