Translation:I am still young. I still want to go out.
What is the meaning of 'go out' here in the case of 'đi chơi'. Does 'I still want to play' encompass a similar meaning?
"Đi chơi" means "go out" in the sense of an outting like a bar, a zoo, a park, a friend's house party, etc. So we're going out of our house to have fun (and play). I hope that helps?
Sylvia explained it quite well: you need to go out of your house to have fun. if you just want to stay home and play on a games console, or throw a party at home, you won't say "đi chơi".
