There is a very interesting record in Zi Jian: In November of the first year of Chen Zhide (A.D. 583), Pai Cheng rode off to Feng, while Chang was sent to Sui. Chen heard that Emperor Wendi of Sui Dynasty and Emperor Wendi of Sui Dynasty looked different, so he asked him to go back with a portrait. When Chen saw the portrait of Emperor Wendi of Sui Dynasty, he said loudly, "I don't want to see this man!" " Immediately ordered the painting to be thrown away.

According to Sui Shu's records, Emperor Wendi of Sui Dynasty was "a dragon chin with five pillars on his forehead, with clear eyes and a text in his hand, which was long and short and heavy." As can be seen from the above description, Emperor Wendi of Sui Dynasty has five "oddities" in appearance: first, his forehead is prominent, and five protruding parts are directly inserted into the top of his head from his forehead; Second, the mandible is very long and prominent; Third, the eyes are sharp and aggressive; Fourth, the palm print looks like the word "Wang"; Fifth, the upper body is long and the lower body is short.
