As the moon rises and the tide gently recedes, Penghu's intertidal zone gradually reveals rock crevices, puddles, and rich coastal life. Residents step onto the waves holding lamps, continuing the generational wisdom of "Zhao Hai" (illuminating the sea), searching in the glimmer for shells, crabs, octopuses, and the ocean memories left behind by the tide.
The artwork uses light and shadow to depict the daily life of Penghu people who live by the sea and work with the tide, allowing viewers to feel the profound human emotion of respecting, knowing, and cherishing the ocean amid the flowing light and shadow.
