《庄子·杂篇·列御寇》
卖浆人只不过是做些小本的饮食买卖，没有多少赢余，获利微薄，权势轻微，还如此待我，更何况是万乘的国君呢？
夫浆人特为食羹之货，无多余之赢，其为利也薄，其为权也轻，而犹若是，而况于万乘之主乎！
A vendor who earns his living by selling drinks is merely a retailer, and his capital is not much. He makes a small profit and has little power. He behaves toward me in this manner. What about the king of ten thousand chariots?
