Luohe's history stretches back over 8,000 years to the Jiahu Neolithic site, one of the most important archaeological discoveries in China. Excavated in the 1980s, Jiahu revealed the remains of a sophisticated ancient settlement with evidence of early rice cultivation, animal domestication, and — most remarkably — inscribed symbols on tortoise shells that may represent the earliest form of Chinese writing.
During the Han Dynasty, the area was part of Yingchuan Commandery. It was in Luohe that Xu Shen completed Shuowen Jiezi in 121 AD, a work that required 22 years of scholarship and analysis.
For centuries, Luohe was a modest market town serving the agricultural communities of the surrounding plain. The Sha River provided transportation links that facilitated trade.
The modern transformation began in the 1980s when Shuanghui, then a small local meat processing plant, began its rise. Under visionary leadership, Shuanghui grew from a bankrupt state-owned enterprise into a global food conglomerate with operations spanning multiple continents.
Luohe was formally established as a prefecture-level city in 1986. Since then, it has developed into a modern urban center while maintaining its position as "China's Food Capital."
