Generally, the left hand holds a fork and the right hand holds a knife. Hold the knife and fork from above, and press your forefinger on the knife and fork to use.
Simply put, it is to cut food with a knife in your right hand and then fork it with your left hand.
Press the left end of the food with a fork, fix it, and cut it along the side of the fork with a knife (put the knife vertically on the palm of your hand, press the palm against the bottom of the handle, press the top of the handle with your index finger, and cut off the steak bit by bit). Then the fork can directly tie up the food and send it to the mouth.
