I have kept these three mirrors in case I pass by.
Now Wei Zhi is dead, he died in a mirror!
It means that a mirror made of copper can be used to tidy up your clothes, history can be used as a mirror to know the rise and fall of dynasties, and people can be used as a mirror to know their own gains and losses.
I often use three mirrors to prevent me from making any mistakes. Today, Wei Zhi died, and I lost a mirror.
