This is a sister copy of the Ancient History of Manchuria under the same premises as the ancient scriptures of Korean history had been destroyed by the invaders. With this premise, Mosol starts to explore many issues after the Han invasion to Manchuria. He tackles lots of disputed issues that had been under the thick fog, analyzingthem in depth. Many issues relating with ancient Korean history are discussed. He proposes many new theories. The most striking new findings are that all of Three Kingdoms originated from Manchuria. Wei (??) is the descendant of the original Ye (?) people who settled around the Bohai Bay (???) under the leadership of Namryeo (??). They were close neighbors with Baekjae and were the dominant seafarers. The most disputed topic engraved in the Stele was in the Liaodong Peninsula. It is a fresh look in the academic sense for other scholars. Lee Mosol, MD, MPH
