Are the descendants of the Goguryeo people Han, Manchu, Korean or Japanese?

Today’s Korean nation is a nation composed of Silla people and Baekje survivors. Some Goguryeo survivors fled to Silla, and the vast majority of Goguryeo survivors who stayed in their homeland in the northern part of the peninsula were almost massacred by the Tang army of the Andong Protectorate in the subsequent civil unrest on the peninsula. The survivors in the southeastern part of Jilin and the Liaodong Peninsula were moved by the Tang Dynasty to the Denglai area in Jiaodong, Shandong and Lulong in Hebei, which is today's Yantai, Weihai and Qinhuangdao areas in Tangshan. This part has basically integrated into the northern Han people. The main force of the Goguryeo army and their family members, about 280,000, who surrendered to the Tang army on the Liao River front line, were resettled in Liaoyang by the Tang Dynasty under the leadership of the commander-in-chief Da Zuorong. Later, during the Wu Zetian period, they participated in the Khitan rebellion and fled north to Songhua to escape suppression. Jiang and Nenjiang rivers in the Heilongjiang Basin, combined with the local Mohe people, gave birth to a new nation - the Jurchens, and established the Jurchens' first nation-state - Bohai State. Therefore, the largest remaining ethnic group in Goguryeo is one-half of the ancestors who constituted the Jurchens. If we insist on saying who is the descendant of Goguryeo, it should be the Manchus. South Korea is talking nonsense now, telling lies with its eyes closed, insisting on recognizing Goguryeo as its ancestor. It is estimated that its real ancestor - the historical enemy of Goguryeo, was almost angry at Silla, which was subjugated by Goguryeo. As for the Koreans in China today, the earliest source is that Huang Taiji of the Qing Dynasty conquered Korea twice and captured more than 100,000 captives. Most of them were incorporated into the three banners of the Ministry of Internal Affairs and became domestic slaves of the Qing royal family. They lived together in the east of Shenyang today. Tower area. Later he entered the Pass with the army. Many of these people later became Manchus. Those who stayed in Fengtian outside the Pass lived in clusters, and their language, habits and customs remained unchanged, and they became the Korean people living in Shenyang today. As for the Koreans in the Yanbian area, they were the latest to arrive, and the earliest were no later than the late Qing Dynasty, when they crossed the border to cultivate and settle down. Later, Korea was annexed by Japan, and a large number of Koreans fled into Manchuria. In order to facilitate the penetration of the Manchurian Island (Yanji), the Japanese acquiesced and even encouraged the Koreans to enter Manchuria. Later, when Japan was defeated, the Koreans who stayed in Manchuria and did not return to the peninsula became ethnic Koreans. Today, when you go to Yanji, most Korean families will basically ask about their grandparents who returned to the Korean Peninsula. It can be seen that the history of their migration is short, and they are definitely not the indigenous people of Manchuria as advocated by Korean media and scholars.
