《资治通鉴·唐纪·唐纪七》
李世民准备出发的时候，李建成和李元吉一起商议说： 如果秦王到了洛阳，拥有土地与军队，便再也不能够控制了。不如将他留在长安，这样他就只是一个独夫而已，捉取他也就容易了。 
将行，建成、元吉相与谋曰： 秦王若至洛阳，有土地甲兵，不可复制；不如留之长安，则一匹夫耳，取之易矣。 
When Li Shimin was about to leave, Li Jiancheng and Li Yuanji discussed, saying, "If King Qin goes to Luoyang with land and troops, he will not be able to control it anymore. It is better to keep him in Chang'an. In this way, he will be alone and it will be easier to catch him."
