《南齐书·列传·卷三十》
让刘怀慰以薛渊的名义写信给薛道标表示拉拢收买他的意思，魏得到这封信，果然将薛道标召回，派别的将领代替他。
令为渊书与道摽示购之之意，虏得书，果追道摽，遣他将代之。
Let Liu Huaiwei write a letter in Xue Yuan's name to Xue Daobiao, expressing his intention of buying him off. Wei received the letter, and they did call Xue Daobiao back and replaced him with another general.
