Submarine experience is a self-funded project. We set out on a speedboat and boarded a submarine in the middle of the sea. The boat is underwater. It is introduced in Chinese and can take pictures. But the light is not very good and there are many people. From every window we can see the motions of the seabed. There are many old sunken animals, anchor chains, hull parts and so on. Fish shuttle among them. It's very interesting. The water is very clear and it's a very interesting experience.
