The beautiful Yao and Shun gave way to saints, and the magical Dayu managed water and ushered in the dawn of Chinese civilization. The prosperity of Xia, Shang and Zhou Dynasties and the brilliance of Qin, Han and Tang Dynasties left a distinct impression in the history of Chinese civilization.

Wen Tianxiang, the anti-Yuan general, left a heroic oath with patriotic enthusiasm: "Since ancient times, no one has died unexpectedly, so we should keep an open mind and shine on history." .
