Allusion: This language comes from Yurang, The Four Assassins in the Spring and Autumn Period. During the Spring and Autumn Period and the Warring States Period, the Han, Zhao and Wei clans wiped out their clans. In order to avenge Zhi Bo, Yu Rang went to the toilet to swallow charcoal and smeared himself, and repeatedly assassinated Zhao Xiangzi. Finally, he committed suicide and died, leaving behind the eternal swan song of "a scholar dies for a confidant, and a woman looks after herself."

Meaning: This sentence has become the traditional creed of ancient people in China, which embodies the spirit that people are willing to repay their confidants with death because they are rare. Intellectuals in particular, on the one hand, are honest and upright, "Phoenix is not a barren phoenix tree"; On the one hand, a scholar died for his bosom friend. For example, in order to repay Liu Bei's kindness of "three visits to the cottage" and assist his ancestors, Zhuge Liang made every effort to become a model that ancient intellectuals yearned for and admired.
