In order to expose the hidden writings in the "National History", Dazhan pointed out the hidden writings in Fu Ji, the ministers who were executed by Zhu Yuanzhang under the pretext of the Ming Dynasty, so as to restore the truth. The book Yanshantang Collection is a valuable historical material that can reflect Wang Shizhen's historical thoughts.
One hundred volumes of Yanshantang Collection were written by Wang Shizhen of the Ming Dynasty. This book is called "Part Collection", but it is not a collection of poems and essays, but a historical work. The reason why it is called "Bieji" is because "there is a Zhengsheng collection of Yuanmei poetry and prose, and this is a collection of national and dynasty allusions, which is better than a generation of treasures." Wang Shizhen himself also explained, "Who gave the name Bieji?" ? The inside is not worthy of the political system of Confucianism, and it is also called a separate collection. "Zhou Zhongfu of the Qing Dynasty ridiculed Wang Shizhen, "Because he didn't know that the poems should be called a separate collection." I'm afraid it's not true. With Wang Shizhen's liberal arts, he didn't know this at all.
