《北史·列传·卷六十》
这时，太子杨勇失宠，文帝有废立太子的意思，对高颎说： 有神告知晋王妃，说晋王必定享有天下。 
时太子勇失爱，帝潜有废立志，谓颎曰： 晋王妃有神告之，言王必有天下。 
At this time, Crown Prince Yang Yong fell out of favour. Emperor Wen intended to depose and replace the crown prince and said to Gao Ji: "There is a god who told the Princess of Jin about the King of Jin enjoying the world."
