Cảm ơn nhiều. in my opinion, the best leisure activity for teenagers is playing sports. Firstly, they can exercise their physical health. Secondly, they can make friends with people who have the same interests. Thirdly, some activity good for mental health are a good way to relieve stress. Morever, play sports can increase resistance and helps us fight some diseases. For these reasons, i think their parents should give advice about how they spend time for their leisure activities.
