Large-scale fish rafts for feeding fish floating on the waters off Shenzhen on Thursday.

Some 35 years ago, the city in Guangdong province was just a fishing village.

It has since emerged as the tech manufacturing capital of the world.

Under former leader Deng Xiaoping, it was identified as one of the first of China's special economic zones, an area where foreign investment and entrepreneurship were encouraged.

But fishing still continues today, with nearby coastal areas, such as Nanao Island, off the shores of Shenzhen, bustling with seafood markets and restaurants that draw visitors from out of town, including Hong Kong.
