I said that I certainly don't know as much about Lake Baikal as the locals do.

Sanjay knows the origin of the name of Lake Baikal so well, then you must know more about Lake Baikal!

Peter said that the knowledge about Lake Baikal can be summed up in an encyclopedia. Where do we start?

I said, let's start with the relationship between China and China, which we are most interested in.

Sanjay smiled and said:

- "Linna, you're asking the right question, you know?" Peter's study of history is almost comparable to that of a professional. ”

- "Aha, I'm a history major, and it seems that we have found a common hobby again." I said.

- "Really? I love history very much, Linna, I'm studying history and philosophy in a correspondence course, and I plan to go to graduate school in politics next year. Peter's eyes lit up excitedly, and he touched his glass with me like Sanjay, took a big sip of vodka, wiped his lips and began to speak:

- Historical records record that around the 3rd century B.C., the Ding Ling people in Chinese history were scattered around Lake Baikal.

At the end of the 3rd century BC, Ding Ling was conquered by the Xiongnu and became the ruled tribe of the Xiongnu slave state.

After the 1st century AD, Transbaikalia was active in Xianbei, Gaoche, Tiele and other tribes.

During the Han Dynasty, the Southern Xiongnu under the leadership of Huhan Yedan, re-established the court in the Karabargasun area on the west bank of the Orkhon River, ruled the Xiongnu and its subordinate departments, and wrote to the imperial court to ask the "Shishi Baosai" Ru to guard the northern territory for the Han Dynasty, and the Xiongnu became a subordinate department of the Han Dynasty, and the northern territory under its rule, including the Baikal region, was the territory of the Han Dynasty.

Palace buildings and city ruins of the Han Dynasty have been found near the cities of Abagan and Ulan-Ude, and the unearthed Wadang has the text "Thousand Autumns of the Son of Heaven, Changle Weiyang".

At that time, the cultural influence of the Yellow River basin in China had extended to the Transbaikal region and the Yenisei River basin.

From the 1st century AD, the Mongolian Plateau and the Baikal region successively passed under the rule of the Xianbei regime.

In the middle of the 4th century, the Tuoba Xianbei tribe entered the Yellow River valley to establish the Northern Wei regime, and the Mongolian Plateau was "transferred to its place" by Rouran (i.e., Worm and Ruru). To the north of Jouran there is a high-chariot (dingling), and nomadic herders around Lake Baikal are called eastern high-chariots.

In the middle of the 6th century, the Turks rose up on the Mongolian plateau, and the Turkic tribes and Tungusic people were the masters of the Circum-Baikal region.

The Ankara River basin is a mixture of three Turkic tribes, collectively known as the Uziguli, and to the north is home to the Tungusic people in the upper reaches of the Lena River.

In the middle of the 7th century, the government of the Tang Dynasty of China officially set up administrative structures in the region east of Lake Baikal, and the Xuanzhu Prefecture (Yuwu Prefecture) of Guli Cadres was located on Lake Baikal, the Jilu Prefecture of the Xi Jie Prefecture, the Zhulong Prefecture of the Kurob Prefecture and the Gaowang Prefecture of the Xue Prefecture were located in the east of Lake Baikal.

This is the official establishment of an administrative body by the Chinese government in the Baikal region.

From the 10th century to the early 12th century, most of Transbaikalia lived in a tribe called "Niang Niang (斡 Lang) Gai".

At the beginning of the 10th century, the Khitan people of China rose up and established the Liao Dynasty, which ruled northern China. East of Lake Baikal up to the Primorsky region, it was also under the jurisdiction of the Liao regime.

At the beginning of the 12th century, the Jurchen tribe under the rule of the Liao Dynasty rose up to destroy the Liao, established the Jin Dynasty, and succeeded the Liao to rule northern China.

East of Lake Baikal to the Primorsky region, all under the jurisdiction of the Jin dynasty.

Medieval Mongolian sources confirm that the first Mongol tribes to arrive on the shores of Lake Baikal were: the Ishiles (Ehirigo), the Bugogachin (Bragats) and the Kro (Khorins), and later some Mongols merged into them, such as the Hungotor people, who eventually settled in the Zakam, Tonkin and Ogin Buryat regions in the territory of the Republic of Buryatia in the Arar Krai of the present-day Irkutsk region.

At the beginning of the 18th century, it was inhabited by the Conggol and Saldur peoples.

In 1206 (the sixth year of Taihe), Temujin called "Genghis Khan", established power, and soon unified the Baikal region and the Shilka River basin, which became the territory of the Jin Dynasty, and the nomadic Tsui Nianggai (Uliangha) tribe in the area of the Shilka River and the Onen River in the east of Lake Baikal also became the subject of the Jin Dynasty.

After Kublai Khan, the ancestor of the Yuan dynasty, set up the "Lingbei and other places in the province of Xingzhongshu" in the Mongolian Plateau and the Baikal region north of the desert, and the province was governed in Helin, and the jurisdiction of Lingbei and other places in Xingzhongshu Province included the area east of Lake Baikal, the upper reaches of the Heilongjiang River, the Heilongjiang Xunbei area in the north of Daxinganling City, and the provincial border of Liaoyang and other places in the east was adjacent to the provincial border of Xingzhongshu Province.

The government of the Yuan Dynasty also set up official pastures in the eastern Baikal region, which was under the leadership of the central government.
