Where did you find the ancient documents (imperial edicts, memorials, ancient books) when Yue Ming wrote The Ming Dynasty?

The following are the words of Mingyue, which I reprinted:

"It should be noted that this article describes the official history. The data sources include more than 20 kinds of historical materials and notes of the Ming Dynasty, such as Shi Minglu, Tong Ming Jian, Shi Ming and Shi Nian Pu. Although many popular literary descriptions and expressions are used, most of the historical events and characters in the article, even the dialogue between characters, have historical origins. For the sake of fluency, the source is not.

Therefore, the reference sources of the bright moon in that year are more than 20 kinds of Ming Dynasty historical materials and notes, such as Lu, bamboo slips, Shi Xianian Pu and so on.
