Technology delivers fresh, delicious crabs

NANJING - Yangcheng Lake in Jiangsu province, renowned for producing China's best freshwater crabs, introduced intelligent logistics and blockchain technology this year to ensure freshness and authenticity of the seasonal delicacy.

It's a longtime custom for Chinese to eat crabs in autumn, when the meat is at its best, especially during the Mid-Autumn Festival, on Sept 24 this year, and the holidays that started with National Day on Monday.

The lake's palm-sized crabs have gained nationwide popularity.
