A Non-Chinese realm in modern Yunnan province, active from the late Spring and Autumn period (Chunqiu 春秋) to the Western Han Dynasty (Xihan 西漢). The Dian people had already entered the age of bronze casting and created some interesting and wonderful cultural relics that are very different to the proper Chinese art in shape and appearance. Tilling the fertile fields of the subtropical area, the Dian developed a high-sophisticated technique of rice cropping, but they did not make use of a plough. In 109 emperor Han Wudi 漢武帝 conquered the territory of Dian and established commanderies, but the ruler of Dian was officially installed as king.
