《魏书·列传·卷二》
当时淮南王元他、淮阳王尉元、河东王苟颓都因是旧臣元老受到礼遇，每当有大事时，接进宫中，乘坐人拉车，在朝中拄着拐杖，进退在一起。
时淮南王他、淮阳王尉元、河东王苟颓并以旧老见礼，每有大事，引入禁中，乘步挽，杖于朝，进退相随。
At that time, Yuan Ta, Prince of Huainan; Wei Yuan, Prince of Huaiyang; and Gou Tui, Prince of Hedong were all given special treatment as old feudal lords. Every time there was an important event, they were welcomed into the palace, riding in human-drawn carriages and leaning on their walking sticks in court. They moved forward and returned together.
