Is “Because of his long face, Sun Quan drew a donkey's face on him at a banquet.” true?

According to the annotation in Pei Songzhi's commentary on the Records of the Three Kingdoms, Book of Wu, Biography of Zhuge Ke, citing the Records of Jiang Biao, Zhuge Jin's face was long like a donkey's. Sun Quan wrote 'Zhuge Ziyu' on a donkey, and his son added 'of the donkey'.
