《礼记·玉藻》
所有进献的美食，都由主管膳食的官员负责接受。大夫之所以不亲自去向国君进献物品，是担心劳动国君答拜自己。
亲在，行礼于人称父，人或赐之，则称父拜之。
All delicacies presented to the ruler were accepted by the official in charge of food and beverage. The reason why a high-ranking official did not present items to the ruler in person was because he did not wish to inconvenience the ruler by forcing him to return the courtesy.
