Although the cultural relics will not speak, and there is no truth in history, the discovery of the Liudingshan Ancient Tombs (Bohai Ancient Tombs) in the remaining gaps has made the Northeast civilization more abundant. In this ancient and magical millennium ancient temple, the Bohai civilization is a great glory of the Northeast civilization and a treasure of the Chinese civilization. I only hope that these remaining gaps will flourish with fresh blood and make our cultural lifeline more prosperous.
