What is the difference between the use of the focus ring and the zoom ring?

Focus ring: A focusing method that adjusts the camera lens by manually turning the focus ring to make the photos taken clear. This method relies largely on the human eye's judgment of the image on the focusing screen. As well as the proficiency of the photographer and even the vision of the photographer. Zoom ring: By rotating the zoom ring, the lens can move to zoom in and out of the scene to be photographed. The greater the optical zoom factor, the farther the scene can be photographed. In daily shooting operations, it is generally necessary to zoom first and then focus.
