From the perspective of the origin of the surname, the Subi people are from Xiqiang and also belong to the beggar surname. "The Classic of Mountains and Seas, The Classic of the Sea" clouds: "Boyi's father gave birth to Xiyue, Xiyue gave birth to the first dragon, and the first dragon was born to Qiang." Qiang begging surname. "Bo Yi's father, also known as Bai Yi's father, was a master who cultivated in Hunan during the emperor's reign. According to the records of "Li Ji", Bai Yi's father Da Liang, Dali Chimin, and Zhuan Xuan all lived between Hunan and Li, and they were close to each other. Xu Shen of the Eastern Han Dynasty said: "The word Qiang, from the sheep from the people, means the shepherd." "Father Bethis is one of the ancestors of the Subians. There are beggar surnames among the Subi tribes. The Subi people have long lived with the later Tibetans and were annexed by the later Tibetans. The Tibetans branched out from the Qiang that entered the Tibetan Plateau. Some of the surnames among the Suvi people are derived from Zhangzhung and Tibet, including Niang, Wei, Dong, Bolan, and other surnames of the six Tibetan tribes. Among them, the White Wolf Clan of the Brands is a female-centered tribe. According to the "Biography of Zampu" part of the "Documents" and the "Minister's Legacy" part of the "Five Testaments", the Wei family served as the Great Treatise of Tibet: Wei Chise Xiangnian, Wei Chisu Jiezang, Wei Nangshu Xu Zan, and Wei Jiaduo Redani. In the Great Treatise, it is Wei Su Nang, and the tax collector is Wei Su Nang.

The origin of the Suvi surname is more complex. Subi is a female-centered country. According to the "Banquet of the Sage", "The Records of Tibetan Princes and Ministers", "Dunhuang Ben Tubo Historical Documents", etc., the Qinghai-Tibet Plateau Zhufang States Subi, Zhangxiong, Tubo and other early children were all from their mother's surname. The peaks of the Himalayas are named after the goddesses. The 12 Danma throughout Tibet are also goddesses. "The Book of Sui: The Biography of the Female Kingdom" records: "The female country, in the south of the Green Mountains, has a female king in its dynasty. The king's surname was Subi, and he reigned for twenty years. The queen's husband, known as Jin Ju, does not know political affairs. The husband in the country only takes conquest as his business. The mountain is a city, five or six miles square, and there are thousands of people...... There is a little queen who knows the country's politics. There are asura gods in mundane things, and there are tree gods......

In the sixth year of the emperor's reign, he sent tribute, and then refused. "The Subi State established a tributary relationship with the Sui Dynasty in the sixth year of the Emperor's reign. The "General Dictionary" women's country article records: "Women's country, Sui Shi Tongyan." In the south of the Green Ridge, the country has a woman as the king, the king's surname is Subi, and the queen's husband is called Jin Ju...... The emperor sent an envoy to ask for tribute. The "Old Tang Book" of the Tang Dynasty recorded: "The East Woman Country, the West Qiang Species...... The vulgar woman is king. It borders Maozhou in the east and Yazhou in the southeast, and is separated by Luo Numan and Baiwolfyi. Its territory is nine days from east to west, 20 days from north to south, there are more than 80 cities of all sizes, the name of its king is Kangyan River, there is a weak water flowing south, and the cowhide is used as a boat to cross. "During the Tang Dynasty, there were more than 80 cities of all sizes, and the land was short from east to west and long from north to south. The "New Tang Dynasty Book" said: "The customs of the Subi country are light on men, and the noble women have servants." According to the Tang Hui Yao, in the Subian kingdom, the woman was the head of the family and had multiple husbands. Therefore, the surnames of the various tribes in the Subi country are more complicated, and among the surnames of different tribes in different periods, there are both matrilineal and patrilineal families; There are both ancient Qiang surnames and surnames of other tribes.

From the perspective of the origin of the surname, the Subi Kingdom once became the overlord of the Western Regions during its most powerful period, and some of its clansmen's surnames naturally came from the surname Zhaowu Jiu. The so-called nine surnames of Zhaowu are actually Kang, An, Cao, Shi, Mi, Shi, He, Mu, Bi and other nine surname countries, all of which are Zhaowu. (The so-called Zhaowu nine surnames can be said here, these nine countries are named after their surnames, among which the Mu State is also called Mulu and Moufu, which is located at the southwest end of the Sogdian region, which is the Mali region of Turkmenistan in later generations.) Bi country is also known as Wu land, cutting land, located in the west of Anguo, also known as Xi'an. Shi Guo, also known as Kashana or Pingsha, is located at the southeastern tip of the Sogdian region, which was known as the state of Pingsha during the Tang Dynasty. He Guo, also known as Guishan, is located between Kangguo and Anguo, and was Guishan Prefecture during the Tang Dynasty. Mi country, located in the southeast of Kang 100 miles, Tang Dynasty for the south of the state. Shiguo, also known as the tongue, ochre, Zheyi, etc., is located at the northeastern end of the Sogdian region, near present-day Tashkent, and was the Dawan Governor's Mansion during the Tang Dynasty. Cao State is divided into East Cao, Middle Cao, West Cao and so on. Anguo, also known as the State of Rest, is located near Bukhara and was known as the state of Anxi during the Tang Dynasty. Kangguo, also known as Xi Wanjin, Sama Xuan, etc., was originally the fief of the ancient Gonggong clan, located near Samarkand, and the Tang Dynasty had set up the Kangju Governor's Mansion).

After talking so much, I just want to say that this Subi country is actually the famous "Xiliang Daughter Country" in Journey to the West, if you want to unify the plateau, you must conquer Zhangxiong, and if you want to conquer Zhangxiong, you must take this Subi country. As the lord of a country and the commander of an army, Li Zheng is well aware of the truth that before victory, defeat is calculated, knowing oneself and knowing the enemy, and not being defeated in a hundred battles. Long before the departure of the army, Li Zheng sent a large number of scouts (that is, the so-called scouts) and spy agents to enter the Subi and other countries, to find out the distribution and population of all the tribes on the plateau, and to infiltrate and buy some of the natives of the plateau who were oppressed and suffered, and then a steady stream of information was continuously transmitted back to the joint staff headquarters in Ledu (the capital of the Haixi State established by Li Zheng) with carrier pigeons. They first gathered all the situations and directly displayed them on the sand table, and then analyzed and formulated a suitable military battle plan according to the situation on the sand table.........

With the collection of more and more complete information, Li Zheng also felt that his pressure was a little great, he began to estimate that the population of several countries on the plateau was only hundreds of thousands of people, so it looks completely wrong, now the statistics have more than doubled, the population is close to two million, and this southern expedition, Li Zheng plans to dispatch 70,000 cavalry, that is to say, his army must have a block of 100 to put the Subi, Zhangxiong and other plateau countries down, how is this good?

With the statistics of the distribution of population and tribes, as well as the military strength of the nobles of several countries on the plateau, it was sent to Li Zheng here, after careful study, Li Zheng smiled, these plateau countries said that they were countries, but in fact, they were at most in the early stage of slave society, and even many tribes were still at the end of primitive society. What's so hard it is to fight a lot of tribes who know well that they still have sticks and stones in their hands?

However, Li Zheng also knows that the poor mountains and bad waters come out of the people, although these barbarians are poor, but the combat effectiveness is quite not bad, otherwise after the rural cadres unified the plateau, they can also have contacts with the powerful Tang Dynasty, and even invaded Chang'an, the capital of the Tang Dynasty.
