《隋书·列传·卷十》
高祖对他恩宠既变，外加谗言离间，高祖为父的慈爱，立即隔于人理；父子之道，于是灭了天性。
恩宠既变，谗言间之，顾复之慈，顿隔于人理，父子之道，遂灭于天性。
Since Emperor Gaozu was no longer gracious to him and with the addition of slander and alienation, Emperor Gaozu, as a father, immediately kept his love away from humanity; the path between father and son, therefore, extinguished the nature.
