You kids who don’t know hardness or strength in the comments.
When a wooden stick and a glass stick frame are rubbed against each other,
Does the tree get scratched? Then glass is better than wood
The degree is high:
A wooden stick and a glass frame collide with each other.
Does the glass break? Then wood is better than glass
Is the intensity high?
