《战国策·楚一·江乙说于安陵君》
安陵君泪流满面，上前对楚王说： 我在宫内和大王挨席而坐，出外和大王同车而乘，大王百年之后，我愿随从而死，在黄泉之下也做大王的席垫，以免蝼蚁来侵扰您，又有什么比这更快乐的呢！ 
安陵君泣数行而进曰： 臣入则编席，出则陪乘。大王万岁千秋之后，愿得以身试黄泉，蓐蝼蚁，又何如得此乐而乐之。 
With tears streaming down his face, Lord Anling came forward and said to the King of Chu, "Within the palace, I have sat beside Your Majesty at banquets, and outside the palace, I have shared Your Majesty's carriage; when Your Majesty has been a hundred years in the grave, I wish to follow you in death, and beneath the Yellow Springs, serve as your cushion, so as to prevent ants from disturbing you; how could anything be more delightful than that!"
