《汉书·传·霍光金日磾传》
有郎官上书说： 周太王废掉太伯而立王季，文王舍弃伯邑考而立武王，衹要对国家有利，即使是废黜长子而立少子也是可以的。
郎有上书言： 周太王废太伯立王季，文王舍伯邑考立武王，唯在所宜，虽废长立少可也。
A civil official wrote a memorial stating: "King Zhou Tai废掉了太伯 and in his place established King Ji, and King Wen abandoned伯邑考 and in his place established King Wu. If it will benefit the state, even if it means passing over the elder son and choosing the younger, it can be done."
