If you nothing to do at night and staying near Jonker Street you can learn how to 'Taichi'. Only 20 meters from Jonker Street and I see all are old people who doing "Taichi'. What is Taichi? You can ask Dr Google and he give the best answer hehehhee. What can I say is Taichi is a slow movement of body and hand .
I'm try to focus and to absorb energy from stomach hahahaha
