A group of farmers from Yonglian village in the coastal city of Zhangjiagang, which specializes in fish breeding, bought an old second-hand steel machine from a local factory and started their steel business 30 years ago.

Decades later their business, called Jiangsu Yonggang Group Co, is one of the most renowned steel production bases in China, and achieved sales revenues of 35.5 billion yuan ($ 5.9 billion) in 2013.

The machine that the villagers originally bought is on display in the Yonglian Exhibition Hall and is a symbol for the rapid development of the town.
