The six people who encouraged Yuan to become the emperor were compared to the "Six Gentlemen Soup" which had a tonic effect, and Chen Huan, Chen Shufan, and Tang Xiangming, who led to Yuan Shikai's loss of power, were compared to the "Two Chen Soup" which had an expectorant effect. The terms "Six Gentlemen" and "Er Chen Tang" are not just acronyms, but also sophisticated metaphors. Those who help Yuan correspond to "Six Gentlemen Zi", which has a tonic effect, and those who go to Yuan correspond to "Er Chen Tang", which has an expectorant effect. It can be said that from the words to the meaning of the neat ah.

The Six Gentlemen of Chuanan (in the early years of the Republic of China): Yang Du, Sun Yukun, Yan Fu, Liu Shipei, Li Xieru, and Hu Ying, who advocated Yuan Shikai's restoration of the empire.
