Along China's eastern coast, a new relationship between the sea and the people who visit it is taking shape. In Yantai, a flower-shaped offshore structure called Genghai No 1 invites visitors not merely to gaze at the ocean but to enter its working rhythms — watching fish harvested, learning marine ecology, and eating what the sea provides. The facility embodies a broader shift in how China is beginning to understand its 32,000 kilometers of coastline: not as a boundary between civilization and resource, but as a living system where economy, education, and experience can sustain one another.
