《资治通鉴·唐纪·唐纪十二》
太子害怕李泰威胁自己的位置，便派人诈称为魏王府典签上书言事，都拆说李泰的罪过，太宗敕令逮捕这些告状人，查无所获。
太子畏其逼，遣人诈为泰府典签上封事，其中皆言泰罪恶，敕捕之，不获。
The crown prince was afraid that Li Tai would threaten his position, so he sent people to pretend to be the clerk of the Wei palace's archives to present a memorial to the throne. They all accused Li Tai of crimes. Emperor Taizong ordered the arrest of these accusers, but no evidence was found.
