Before the rise of Nanzhao, the main residents of Erhai Lake in Xi were Bai Man and Wu Man in the north. The river is quite weak, and some tribes have made six imperial edicts with Uman as the chief. The meaning of the imperial edict, or the imperial edict is king, or "at first, the six barbarians did not submit to each other, and every time the emperor (Tang Dynasty) rewarded him with the imperial edict, it was called the six imperial edicts" ("Preface to Tang Lu's Plan to Chengdu"). In the past, both theories said yes. The so-called imperial edict is the great leader, chief executive. The names and addresses of these six imperial edicts are as follows:

(1) Mongolian imperial edict-living in the north of Weishan County to Yangbi County, also known as sample imperial edict.

(2) The more analysis of imperial edicts-also known as imperial edicts of Mo Yao (Momo tribe), they live in Fengyi County to Binchuan County.

(3) Langqiu Zhao-lives in Eryuan County.

(4) Article (Yin Teng Shan Té ng Sh m: n)-Living in Deng Chuan County.

(5) Shi Langzhao-living in the northeast of Langqiong, looking for a city. Wave dome, winding and wave application are collectively called three waves.

(6) Meng Shezhao-lives in Weishan County. Among the six letters, the Mongolian residence letter is in the south, so it is called Nanzhao.

The forces of the six imperial edicts are roughly equal, and they do not give in to each other. Among them, the Mongolian imperial edict and the Vietnamese imperial edict have the largest territory and the strongest forces, and the Mongolian imperial edict is weaker than the above two imperial edicts.

Meng, the ancestor of Nanzhao, moved to Meng Shechuan (Baoshan County, Yunnan Province) to avoid the enemy. During the reign of Emperor Taizong of Tang Dynasty, Zhang (Zhang is the surname of Bai Man), the chief of Meng Luxury, was anxious to give way to Nuluo. In 653, Luo Ji, a slave, sent his son Luo to Korea and appointed Luo Ji, a slave, as the secretariat. In 654, Meng Da ordered Yi Li to accept the manager of Yaozhou Road. Zhang's request for abdication, the daughter Luo's sending her son to the DPRK and her request for protection in the Tang Dynasty were probably related to the intrusion of the Mongolian imperial edict. During the reign of Xianheng in Tang Gaozong, Wang Renqiu, the leader of Xiguan, was used as the general to pacify chaos in the Tang Dynasty. Wang Renqiu's Inscription says, "When Xian Heng was old, dogs and sheep (referring to Meng Lian) were greatly disturbed, and the owl would lose Tianjin (Tang Bing was defeated), and the culprit should not be punished." It can be seen that Meng Lian was harassed for many years and moved northward to make samples after the defeat. Nanzhao acquired the land of Yangguazhou (Weishan County, Yunnan Province) from Tang Gongshun.

Wu Zhao and Heman tribes were threatened by Tubo and often abandoned the Tang Dynasty to join Tubo. Nanzhao has always been attached to the Tang Dynasty, so it was supported by the Tang Dynasty. 1773, Emperor Xuanzong of the Tang Dynasty made Nanzhao Piluoge king of Taideng County. In the second year, Pirog sent Zhang Jiancheng, a consultant, to the court. In 737, Pirog defeated Herman and took Taihe City (Dali County). The following year, Emperor Xuanzong of the Tang Dynasty conferred the title of Meng Guiyi on Piluoge and became the king of Yunnan. According to "The Story of Sealing the King", the reason for sealing the king was that the various departments of the river sneaked into the dog (Tubo), and Meng Guiyi led the troops to make meritorious deeds. In 738, Pirog sought to push his luck and annexed five imperial edicts. It is suggested that Wang Yu, an envoy of our time, be built, and six imperial edicts should be combined into one. Wang Xian asked the court for approval. Emperor Xuanzong of the Tang Dynasty wrote to Wang Yu that he was loyal and fought against westerners. "He controlled both ends (including the Tang Dynasty and Tubo), so it should be broken." At that time, Tang and Tubo fought for the city and the war was fierce. Piluoge's attack on the five imperial edicts had the effect of containing Tubo, and it was not because Wang Yu took bribes that he asked for it. Peluge sent troops, and the Tang Dynasty sent envoys (eunuchs) Wang and Yu Shizhen to participate in the military. First, they destroyed the analysis, then destroyed Sanbo, and then destroyed Meng Zhang. Soon, they unified six imperial edicts and established Nanzhao State in the Xi River area. In 739, Piluoge moved its capital to Taihe City.

Tang Li helped Nanzhao unify, originally to make Nanzhao try harder to contain Tubo. Pilog took advantage of the contradiction between Tang and Tubo to win on Tang's side. After the victory, Nanzhao and Tang each had their own opinions. King Nanzhao is a barbarian, but his subjects are white barbarians. It is reasonable to annex the west to the east and establish a white barbarian country. However, in order to protect Guan, Nanzhao tried harder to attack Tubo. In this way, although the two sides still maintain good relations, in fact, irreconcilable contradictions have occurred. In 745, our envoys Zhang Qiu (surname) and Joan of Arc sent envoys to Yunnan, which didn't conform to the words of Pilog, and Pilog was very dissatisfied. In 748, Pirog died and his son Grofeng succeeded him.
