In the early morning in Chaoshan, south China's Guangdong Province, the sea still holds a trace of the night's glow, while along the horizon a line of white egrets cuts across the sky. Fishing boats glide quietly back to shore, the day's catch spread out on the docks, silvery scales flashing. People bend to sort the seafood, hands moving briskly. In the salty sea breeze, songs rise from groups of elders gathered together, laughing as they call out to passersby, "Come, sing with us!"
