via Shine News, 07 December 2021: A feature on the Dian Kingdom in Yunnan province.
There is also an intriguing story about the discovery of the ancient kingdom of Dian.
The monumental history book of ancient China “Shiji,” or “Records of the Grand Historian,” written by Sima Qian, suggested that during the Warring States Period and the Han Dynasty, there was a state called Dian in today’s Yunnan.
However, apart from the several hundred words recorded in “Shiji,” no more historical documents about the state had been found. As such, the state faded into oblivion.
Evidence of the existence of Dian reappeared in 1992 when a diver named Geng Wei accidentally discovered some stone plaques with thick moss above them at the bottom of Fuxian Lake in the city of Yuxi, about 60 kilometers from Kunming.
