《晋书·列传·第三章》
到了文帝为晋王时，王祥与荀频前去拜见。荀颉对王祥说： 相王地位尊重，何侯对他已经恭敬了，如今应当跪拜。 
及武帝为晋王，祥与荀顗往谒，顗谓祥曰： 相王尊重，何侯既已尽敬，今便当拜也。 
When Sima Zhao was bestowed the title of Prince of Jin, Wang Xiang and Xun You paid a visit to him. Xun Yu told Wang Xiang: “Prince Zhao is highly respectable, and Lord He has shown respect to him. You should bow before him.”
