Changbai Mountain belongs to North Korea.

The northern part of the Korean Peninsula, that is, the area north of the Han River, has been the territory of China since the Western Han Dynasty, when four county offices were set up to implement effective management. Today's Koreans are three backward and ignorant Korean aborigines living in the south of the peninsula. Goguryeo and Baekje were destroyed in the Tang Dynasty, occupying four-fifths of the peninsula. Silla people, descendants of three Han aborigines, are embarrassed to talk about a corner of the peninsula. Silla people will not think of gratitude for the reconstruction of the Tang Dynasty, but have a greedy heart for the whole Korean peninsula. With the secret instigation and support of Silla, Koguryo and Baekje immigrated constantly, and the Korean Peninsula was in turmoil. The Tang Dynasty suppressed it for 80 years, and almost wiped out Goguryeo and Baekje adherents on the peninsula, but it never held water. Finally, it was forced to move to Liaoyang in Anton Khufu, Pyongyang. Silla then took advantage of the situation to occupy the Korean peninsula south of Datong River.

Until the end of Yuan Dynasty and the beginning of Ming Dynasty, Datong River was the dividing line between China and Wang. Zhu Ming and Kitahara fought in Liaodong. Wang tried to seize the opportunity to occupy the area north of Datong River, and even attempted to spy on Liaodong. North Korea's general Li Chenggui rebelled, overthrew North Korea and established a new dynasty. The new dynasty carried out great and humble diplomacy towards Zhu Ming and asked Zhu Yuanzhang to give his new dynasty a name. Zhu Yuanzhang named it Korea. In order to reward North Korea, the monks generously allocated the territory north of Datong River to North Korea with a stroke of the pen. North Korea slaughtered and drove away the Jurchen tribe who had lived in Jiangbei for generations, and finally reached the Yalu River and Tumen River.

Changbai Mountain has always belonged to the territory of China. Jurchens who have lived on both sides of the Yalu River and Tumen River for generations regard this mountain as a sacred mountain and a sacred place where Abu Kahankuli lives.

Koreans were originally Silla people, descendants of three Han aborigines, including Baekje people and a few Koguryo refugees. However, they shamelessly assume that Koguryo people are descendants, put forward unreasonable territorial claims to Koguryo's homeland, including Liaodong Peninsula and parts of Jilin, and instilled this wrong view of history internally for a long time. In 1950s, when China and North Korea demarcated the border, North Korea claimed the territory of New China, including Liaodong Peninsula and a large area of northeast territory of ancient Fuyu country in eastern Jilin.

At that time, New China attached great importance to this, gathered a large number of historians, collected and sorted out countless historical classics, and studied them, especially the history of Koguryo, which was systematically studied for the first time in the history of China. China's research found that after Goguryeo's death, some of the adherents who stayed in the northern part of the Korean Peninsula were moved to the boarding area of Jiaodong Peninsula today and Lulong area in eastern Hebei, that is, Feng Run, Luanzhou and Laoting areas in Tangshan today. These people have long been integrated into the Han nationality in northern China. At that time, there were more than 200,000 people in Koguryo's main force who surrendered to Tang Jun at the front line of Liaohe River, with nearly 300,000 family members. Under the leadership of its commander-in-chief, there were more than 500,000 people in total, and they were placed in Liaoyang by Tang. After participating in the Qidan rebellion, in order to escape the attack of Wu Zetian, the Lisu people fled to the north, moved to Songhua River and Heilongjiang Province, and combined with the people living there to form a new nation-Jurchen, and established the first country in the history of Jurchen, namely Bohai State. The remaining Koguryo immigrants in the northern part of the peninsula were basically killed in Tang Jun's subsequent suppression of rebellion, and only a few fled to Silla.

Therefore, New China believes that the Korean nation is not Koguryo, and it has no historical inheritance and inheritance relationship with it, so it has no right to make any territorial claims to Koguryo's homeland, so it categorically rejects its unreasonable claims. However, North Korea shamelessly proposed to China that Baitou Mountain (known as Changbai Mountain by Koreans) was once an important base for Kim Il Sung to carry out armed guerrilla struggle against Japan, and it occupied a sacred and lofty position in the eyes of the Korean people. People hope that men in China can live beyond life and give them a place for future generations to pay tribute to them. At this time, Mao acted as Zhu Yuanzhang's second historical role, giving one-fifth of the Tianchi area of Changbai Mountain to North Korea. Changbai Mountain, which has been China's territory for generations, has become a part of the border between China and North Korea.

South Korea has long conducted deceptive historical education and propaganda at home and abroad, telling lies with open eyes, recognizing Koguryo as the ancestor without crying, and claiming to recover the original lost land in Manchuria. This is also the reason why a large number of Korean tourists openly and illegally demonstrate when traveling in Changbai Mountain. Later, it developed into a vicious incident that some Korean athletes ignored the rules of international sports competitions when they participated in the competition in China, and printed banners about why Baitoushan was their demonstration, which trampled on the sportsmanship and morality.

Koguryo is a nation that has disappeared. Even if there are inheritance and inheritance problems, Manchu should be the undisputed heir, and Koreans are not allowed to confuse people here and fish in troubled waters.
