What's the taboo if Tai Chi Eight Diagrams Mirror is broken?

It doesn't matter, change it, just choose a good day to change it. But remember to change it and don't hang it for too long. On the one hand, it is useless if it is broken, on the other hand, it will affect the appearance and easily remind people of some unnecessary things. Wrap the old ones in red paper (you can also use newspapers if you don't care too much) and throw them away.
