Pilog (? -748), also known as Piluoge, the fifth generation imperial edict of Mengshe, the son of the first generation king of Nanzhao. In 728, St. Ropi died of illness, and Ropi succeeded to the throne, defeating Dong 'erheiman and setting up Hedong County. Emperor Xuanzong of the Tang Dynasty named Piluge King of Taideng County. In February 729, the Tang Dynasty defeated Tubo and captured the salt source of Kunming (now Yunnan salt source). Among the six imperial edicts, Abrupt Imperial edict, Boqiong Imperial edict, Shi Lang Imperial edict and Heman Imperial edict belong to Tubo, while Yue Imperial edict, Mongolia Imperial edict and Mongolia Imperial edict (Nanzhao) belong to Tang Dynasty. Nanzhao was the strongest at that time and wanted to unify the six imperial edicts. In order to alleviate the border dispute with Tubo, the Tang Dynasty supported Nanzhao to unify the tribes. In 737, the Tang Dynasty sent an imperial envoy to assist Nanzhao to capture Shihecheng and Shiqiao, occupy Taihe, attack Dali, pursue Heman, and then continue to annex the imperial edict. In the 26th year of Kaiyuan (738), with the support of the Tang Dynasty, Piluoge defeated Tuotuo, Langqiong, Luo Jun, Shi Lang and Luo Dian, further analyzed the imperial edicts and merged five imperial edicts. In the Tang Dynasty, Pirog was promoted to King of Yunnan, and his name was restored. Nanzhao Kingdom was established on the basis of Hull River (now Erhai Lake) west of Piluge. The following year, he moved the capital to Taihe City (now Dali). In 748, after his death, luo feng was appointed king of Yunnan in the Tang Dynasty. Some Lao people say that he is the founding monarch of Laos, Khumbulun.
