In my impression, there is a Children's Palace in Doumen Gymnasium, Zhuhai, which often holds calligraphy competitions, music competitions and scooter competitions. There are various training courses every winter and summer vacation. Sign up if you want to learn swimming!
There is also a Qianpu Reservoir in Qianpu Town, Zhuhai, where there is a special swimming pool, which is very suitable for beginners to swim there.
