《汉书·传·张周赵任申屠传》
当时高帝想废太子，立戚姬之子如意为太子，大臣们坚持劝谏争辩，都没有成功，皇上由于留侯张良的计策才作罢。
及高帝欲废太子，而立戚姬子如意为太子，大臣固争莫能得，上以留侯策止。
At that time, Emperor Gaozu wanted to depose the Crown Prince and install Consort Qi's son, Ruyi, as Crown Prince, but the ministers persistently remonstrated and argued, and none were successful; it was only because of Marquis of Liu, Zhang Liang's plan that the Emperor desisted.
