Pingtan Blue Tears is a natural wonder created by the bioluminescence of marine organisms like Noctiluca scintillans and sea fireflies. The peak season is from April to August each year—on beaches dotted with windmills and stone houses, you can reach out and touch what seems like a flowing galaxy, capturing stunning, wallpaper-worthy photos with every shot. As the blue glow rises and falls with the waves, and the sea breeze carries fluorescence over your ankles, all weariness is gently soothed by this tender blue.
