The first time I took the Xiguipu submarine, it was quite novel. You can buy tickets online. It is much cheaper than spending 55,000 won on the spot to buy tickets. There are many tourists and many Chinese. It is estimated that it has been a popular tourist project. Several working brothers can speak a few Chinese. The submarine sank about 40 meters to the seabed. There was a diver who gave a full-time performance to feed the fish and say hello. The fish followed him swimming around. I only saw some small fish and a large soft red coral on the seabed. I didn’t see the sea turtle. I can imagine that so many shifts float up and down every day. It scared away big fish and other big marine life. It's a strange species of human being while promoting the protection of the marine environment and destroying the marine environment
