When you've seen how birds and animals live, you cannot bear to see them killed; when you've heard how birds chirp and animals cry, you cannot bear to eat their meat. Therefore, a man of honor has his kitchen placed out of sight and hearing (or keeps away from his kitchen).
君子之于禽兽也,见其生,不忍见其死,闻其声,不忍食其肉,是以君子远包厨也。
