The title implies that, which I think is the aim. It’s a little clickbaity and probably intended to cause that exact reaction. The article itself doesn’t really make that implication as strongly.

Construction of the Great Wall is actually considered a major reason for the fall of China's short-lived first empire (Qin, BC 221-206). By forcing people into inhuman labor, it fostered rebellions.

China did crumble. It was conquered by the tribes the Great Wall was (possibly) meant to keep out. Then it overthrew them. Multiple times.

You should read the article and find out for yourself. Let us know when you're done!

Edit: Fair enough.
