Blender camera view cannot render anything. What's going on here?

I have never used blender, but it should be similar to 3Ds max. Generally speaking, it is difficult to find the problem, because your camera position is blocked by something like a wall, but it is not displayed in the 3D window. You can try to move the camera and then render the field of view of the X camera to see if it can be solved.
