Based on the remains of the Former Han dynasty in Joyang, author has investigated the political situation of this area in this paper. In general, it is suggested that the domain of China extend to Laotung area and the Cheongcheon river valley in Yen dynasty, and the Four Chinese Commendaries created at Pyeungyang area in the Former Han dynasty. But this opinion need to make more study. It is certain that the power of the Yen dynasty and the Former Han dynasty appeared in the Manchurian area, and the central power of these dynasties not extended to the Liao-Ho river. If the Chinese power occupied the whole Manchurian area and the part of the Han peninsular, its remains would discover in all direction. Also, its remains will have to show not the intermittent form but the concrete one. As above, it is certain mat the Chinese power extended to Chinchou and Chinshi in the west of the Liao-Ho river. Therefore, it is suggested that the Yen dynasty settled in this area, and the Former Han dynasty established the perfective and administrative system. Afterward, the quasi-independent political system appear to operate in the Later Han dynasty.
