As long as they cook on the stove, they can be called cooks. And the chef is only the dominant task under the chef. Generally, he is only responsible for frying a few difficult main dishes or more important dishes. Chefs who cook bigger meals generally don't work, you know. There is also a kind of chef who is usually called by others. When you watch TV and teach others to cook, you are usually called a chef. A cook is a man of great responsibility. If it helps you, please adopt it. Thank you.
