Gentleman: Especially a learned and cultivated person. Jun originally refers to the supreme ruler of ancient countries, commonly known as monarch. Gentleman, the original meaning is the son of the monarch. According to the requirements of the ancient patriarchal clan system, the son (eldest son) of the monarch had to be educated in ideals and personality since childhood, so he naturally became a model of personal cultivation. Later, the word gentleman was extended to all people with high moral and intellectual accomplishment.

Scholars were a specific social stratum with a certain position in ancient China society, which later evolved into a general term for intellectuals. At first, they may refer to the leaders and dignitaries of the same clan and tribe at the end of primitive society. After entering the class society, they became a part of the ruling class and still took war as their main occupation. Because in ancient times, "learning was in the government", only aristocratic children above scholar level had cultural knowledge, so scholar became the name of people with certain knowledge and skills.

"Benevolence" was a very broad moral category in ancient China. This refers to the mutual love between people. Confucius regards "benevolence" as the highest moral principle, standard and realm. He was the first to integrate the whole moral standard and formed an ethical thought structure with "benevolence" as the core, including filial piety, brotherhood, loyalty, forgiveness, courtesy, knowledge, courage, respect, tolerance, faith, sensitivity and benefit. Filial piety is the foundation of benevolence and one of the basic pillars of benevolence's ideological system. He proposed to devote himself to the realization of "benevolence", that is, the view of "killing one's body to become benevolence", which had a great influence on later generations.
