It would have to be tai chi, because it is easy to learn and is good for our health.

I would propose skydiving. Some people find it quite expensive and somewhat dangerous but it is one sport which I would want to do. I am sure many students would love to have the experience.

We need a healthy-eating cookery class. Hong Kong's teenagers are usually well looked after at home. Therefore, lots of them don't know how to cook. It is healthier to eat greens with less seasoning. Therefore, a healthy-eating cooking class would be my choice.

If I had a choice, I would introduce dancing. Dancing makes you happy and helps you to relax. Your confidence will also grow if you take part in competitions.
Kelly Yuen Ka-lam, 14, True Light Girls' College
I would add creative rope skipping to my school's extracurricular activities. It is suitable for a wide range of ages and fitness levels. The workout is great for our heart and overall physical health. Through team skipping, we can also learn how to cooperate with others.

I would suggest a gardening club. Looking after plants can help students learn to be more patient. Also, gardening can cultivate students' interest in nature. When you grow a beautiful plant, you will feel like you have achieved something amazing.
