"Dian" was originally an ethnic group on the banks of the ancient Dianchi Lake, and was first seen in Sima Qian's "Shiji Xianyi Liebian Series" The Chu general Zhuang led his people to the Dianchi region, followed the local culture, changed to different customs, and later established the Dian State. During the reign of Emperor Wudi of Han, the Dian Kingdom was incorporated into the territory of the Han Dynasty, and it has been difficult to find a trace since then.
