The words of admonition in Epanggong Fu

The sentence in "Epang Palace Fu" that warns people that they will repeat the same mistakes if they don't learn historical lessons is that "future generations mourn and don't take it, which also makes future generations mourn".

Afanggong Fu is a prose style initiated by Du Mu, a writer in Tang Dynasty. Through the description of the construction and destruction of Epang Palace, this paper vividly summarizes the historical lessons of the Qin rulers' arrogance and extravagance, and warns the Tang rulers, showing the feelings of an upright scholar who cares about the country and the people and helps the people.
