Introduction to the popular science viewing hall: Walk out of the tropical harbor and go up the stairs to the popular science viewing hall. Qingdao Underwater World invested in the introduction of a complete set of video collection and playback systems. Here, visitors can not only receive popular science education, but also enjoy the scene of large water bodies in the underwater world from a first-person perspective through cameras installed on large water bodies. This achieves the combination of marine tourism and marine science education, allowing tourists to increase their understanding of the ocean during the tour.
