Oslo, Cebu, Philippines, began as a fisherman who regularly feeds whale sharks and slowly becomes a place where whale sharks gather. The feeling of traveling with the world's largest fish is thrilling and exciting. Although the whale shark is very docile, it just eats some small plankton and does not attack human beings. It is absolutely safe. It is only when such a giant suddenly appears in front of you. And scared, sometimes when you swim to catch up with the whale shark in front, suddenly you will see that there is a "blood pot" right next to you (another whale shark swims over), roaming in the whale shark group In the meantime, sometimes whale sharks are accidentally caught. Dancing with whale sharks and getting in touch with it, this ocean giant's beautiful figure, smooth skin and rhythmic water absorption are all in close proximity, which is a super dream experience. The only bad thing is that there are too many people watching, and they need to queue for a long time.
