After Wei Zhi's death, Emperor Taizong of Li Shimin famously said: "With copper as a mirror, you can straighten your clothes;" Taking history as a mirror, we can know the rise and fall; Looking at people as a mirror, we can see the gains and losses. I have kept these three mirrors in case I pass by. Now that Wei Zhi is dead, so is a mirror! "

Vernacular translation:

We can dress our clothes with bronze mirrors, know the ups and downs with ancient history as a mirror, and see the gains and losses with people as the foundation. I often use this way to prevent myself from making mistakes, but now that Wei Zhi has passed away, I am missing a mirror.

In the seventeenth year of Zhenguan, Wei Zhi died of illness. Li Shimin was very sad and abandoned the dynasty for five days. Wei Zhi was posthumously awarded as the commander-in-chief of Sikong and Xiangzhou, and was named "Wen Zhen". Li Shimin wrote to Wei Zhi asking for a reburial, but Wei Zhi's wife Shi Pei refused, because life in Wei Zhi was simple and simple, and a luxurious funeral was not the wish of the deceased. Pei's only car was loaded with a coffin, so he called civil and military officials out of the city to see him off and personally wrote an inscription.
