There is a folk saying that "shajin oysters have a glass belly". Shenzhen oysters are not only delicious in quality but also large in size. It is a pity that oysters at original place have become legends and history.
Before Shenzhen became a Special Economic Zone, it was a fishing village that made a living by growing oysters. This is famous oyster town of millennium.
But later, industrial effluents flooded into waters of Pearl River, and water quality pollution changed shallow waters that were originally most suitable for oyster farming: once thick manhole oysters became blue, green and thin.
The oyster breeders in manhole had to look elsewhere. Finally, in a bay in city of Dongtaishan, they found a sea that, in terms of water quality, salinity, temperature, and planktonic microbial content, was best suited to hatch for growing oysters. , Oyster technology and experience is brought there to restore quality of Shajing oysters as much as possible. The grown oysters are then sent back to Shajing to be sold and are still named after "Shajing" to this day.
