When they X-rayed him, the doctors IMMEDIATELY figured out what was wrong. When Li was stabbed, the robber didn't take the knife with him.  No…the entire four-inch blade was left stuck in Li's head!

It was poking into his brain for more than four years…which caused the headaches. And, the doctors say, it absolutely should've KILLED HIM. They have no idea how he's survived.

They performed surgery on Li and removed the blade.

He's now in stable condition.

Here are photos of the X-ray showing Li and the blade now that it's been removed:
