In 643 AD, the outspoken Wei Zhi died of illness. Emperor Taizong was very sad. He said with tears: "a person can see whether his clothes and hats are properly dressed by looking at copper as a mirror;" Taking history as a mirror, we can see the reasons for the rise and fall of the country; Looking at people as a mirror, you can find out whether you have done it right or not. After Kevin·Z died, I lost a good mirror. "

"People can dress up their clothes with copper as a mirror;

Taking history as a mirror, we can know the rise and fall;

Take people as a mirror, you can know the gains and losses.

Without Wei Zhi, I'm dead! "

-This is the best interpretation of Wei Zhi's life value.
