The evolution of family names. In ancient times, the tribal group living in Jinning, Yunnan Province was called "Dian", and the Han people recorded it as "Dian" or "Dian". At this point, the war broke out and the "Dian State" was established. Archaeologist john young thinks that "point" should be a different transliteration of "land".
The evolution of the word "point". In ancient books, the origin of the word "Dian" is explained as the evolution of "Dian", which originated from the backflow of Dianchi Lake. Qiao Zhou's "Foreign Affairs Record" contains that "Dianchi Lake is in Jianning boundary ... the water depth is wide, shallow and narrow, and it looks like a backflow, so it is called Dianchi Lake"; Chang Qu's "Huayang Guozhi" contains "deep and wide, shallow and narrow, like home, hence the name Dianchi Lake". Wang Xianqian's Han Shu Bu interprets Dian as Ding Dian: "Yizhou gambles on lowlands on all sides, and the county's land pool lives alone on the top". Dianchi Lake is located in the watershed of Jinsha River, Nanpanjiang River and Lishe River, with high terrain. However, it is difficult to draw such a conclusion from the knowledge of geographical survey of the ancients. Fang Guoyu's evaluation is "speculative and unfounded". He thinks that "the word' point' should be transliterated in the local dialect, and there is no need to explain it word by word".
The evolution of minority languages. In ancient Yi language and Bai language, Shanping is called "point", and "point" and "point" are simultaneous and universal in translation and writing. Dianchi Lake is famous for its mountain basin, and Yunnan is named after Dianchi Lake.
