When did the map of China become a chicken?

By the end of the Qing dynasty, it became a chicken.

Because of Mongolia's independence, the full border in the north has become uneven, just like the neck part of Inner Mongolia has another prominent part. Besides, after the Second Opium War in the Qing Dynasty, Russia forced China to cede a large amount of land in the northwest and northeast, turning China from a large leafy territory into a chicken.

Extended data:

The historical territory of China is no longer marked as the territory of China;

1, Outer Manchuria

Outer Manchuria refers to an area of more than one million square kilometers sandwiched between Outer Xing 'an Mountains (Mount Stanov), Whale Sea (Sea of Japan), Sea of Okhotsk, Heilongjiang and Wusuli River, including Sixty-four Tun and Sakhalin Island east of the Yangtze River.

2. Tangnurianghai

Tangnu Liang Hai is located in the northwest of Outer Mongolia, bordering Sayanling in the north and Tangnu Mountain in the south. It is a narrow strip between the two mountains, with a total area of about 6.5438+0.7 million square kilometers.

In fact, Liang Hai in East Nuu should be divided into three parts: "Tuva Republic of Russian Federation", the part directly under Russia to the west of Tuva Republic, and Kusugur province of Mongolia. However, because the latter two parts have actually lost the trace of "Tangnuriang Sea", the Tangnuriang Sea area usually referred to is actually the Republic of Tuva in the Russian Federation.

Liang Hai has been the territory of China since ancient times. 1860, because China was defeated in the Second Opium War, Russia forced the Qing Dynasty to sign the unequal Sino-Russian Beijing Treaty in the name of "mediation", which not only forced the Qing government to recognize the legitimacy of the Sino-Russian Aihui Treaty, but also annexed all the land controlled by China and Russia to the east of the Wusuli River.

3. Lake Balkhash region

Lake Balkhash was originally the western border of China. 65438+In the 1930s and 1940s, the border between Russia and Lake Balkhash was still far away. During the two Opium Wars, Russia occupied a large part of China's territory east and south of Lake Balkhash by means of armed invasion and resettlement.
