Introduction to the Time Tunnel: There is a unique fluorescent hand-made mural in the tunnel, which was painted by the famous Japanese fluorescent painting master Mr. Toyama for more than 3 months. The mural describes the formation, development process and future reverie of the ocean, that is, The yesterday, today and future of the ocean; another wonderful thing about the mural: if the fluorescent lights are turned off, the mural will become a white wall with nothing visible, but after the fluorescent lights are turned on, the picture is lifelike and has distinct layers.
