Travel guide, Lonely Planet, is enthusiastic about Haikou Park in Haikou, the capital, so I decided I had to see things for myself.
Haikou Park is a huge leafy and well-maintained park in the town centre. I was surprised to see all sorts of activities going on in the park: table tennis, jogging, singing, ball games, taiji etc.
Dance group: Many dance groups like this one practise in the park to blaring music. They attract a lot of attention from visitors. You're welcomed to join them.
Calligraphy: Using just water, this gentleman uses a huge brush to show off his calligraphy skills. If you think you're equally skillful, he'll gladly lend you the brush.
