Cách sử dụng
The expression "a jack of all trades" refers to someone who has a variety of skills and can do many different things. It is often used as a compliment, but can also have a negative connotation if someone is not particularly skilled in any one thing. For example, you might say "My friend Mark is a real jack of all trades. He can fix a car, cook a meal, and play the guitar." It is generally not used to describe someone who is an expert in one specific area.
