Duke Zhou is the crystallization of our ancient cultural heritage and the wisdom of working people. Although it is difficult to be elegant, it is widely circulated among the people. Later generations wrote it in the name of Duke Ji Dan of Zhou. Everyone must dream. Dreams and people are the same as souls and people. They come with them, go with them and accompany people all their lives. As long as the thinking ability of the human brain is still there, dreams will always exist. Dreams have no hierarchy, no age, no hierarchy, no gender, no Chinese or foreign, but the contents of dreams are different.
