Why does Daqin House hold sheep?

Reese went to visit Lv Buwei, but she was holding a lamb in her arms. This scene is not only funny, but also puzzled everyone. In fact, this scene was not taken casually by the producer, but came from Zhou Dadian. As for the lamb in Li Si's arms, it is actually a gift. It's just this gift, but it's not a gift.

There is a saying in "Zhou Li Chun Guan" that "birds treat six ministers: solitary leather silks, noble lambs, medical geese, pheasants, geese and industrial and commercial chickens".

That is to say, at that time, six kinds of animals were used as meeting gifts, thus distinguishing the grades: princes took silk bundles wrapped in animal skins, Qing took lambs, doctors took geese, teachers took pheasants, ducks, and industrial and commercial people took chickens. Rites and music in the early Zhou dynasty have not collapsed, and the social class is very clear. The rites of the Zhou dynasty are the product of this aristocratic rule.

Of course, the lamb here is not sent to eat. As The Story of the Spring and Autumn Annals says, "The lamb has horns, so it doesn't wait on it, but it is prepared and not used, and it is kind-hearted; Hold it silently, kill it falsely, and die like a righteous man; When the lamb eats its mother's food, it will kneel down and accept it, like a polite person. " At that time, the lamb was a symbol of noble moral integrity and good character.
