We hope to create an underwater world in the city, to promote the beauty and goodness of marine culture. To break away from the traditional third-person perspective, and look at the world from the first-person perspective under the sea. Focusing on immersing yourself in the sea in the form of marine leisure and entertainment "diving" .There are also other spaces related to marine culture in the experience hall. After everyone understands the beauty of the ocean, they can take the initiative to get close to and love the ocean. Start to promote everyone's awareness of cherishing the ocean.
