Chinese philosopher Confucius, originally Kong Fuzi and born circa 551 BC, promoted a system of social and political ethics, emphasizing order, moderation, and reciprocity between superiors and subordinates; after his death in 479 BC, disciples compiled the Analects , which contains a collection of his sayings and dialogues. Teachings of this social thinker deeply influenced Korean, Japanese, and Vietnamese life. 孔子 - Kong Zi 孔夫子 - Kong Fuzi (Kung Fu-Tzu) https://en.wikipedia.org/wiki/Confucius

Mencius (Chinese: 孟子; pinyin: Mèng Zǐ; Wade–Giles: Meng Tzu; Zhuyin Fuhao: ㄇㄥˋ ㄗˇ, most accepted dates: 372 – 289 BCE; other possible dates: 385 – 303/302 BCE) was a Chinese philosopher who was arguably the most famous Confucian after Confucius himself. Also known by his birth name Meng Ke or Ko, Mencius was born in the State of Zou, now forming the territory of the county-level city of Zoucheng (originally Zouxian), Shandong province, only thirty kilometres (eighteen miles) south of Qufu, Confucius' birthplace. He was an itinerant Chinese philosopher and sage, and one of the principal interpreters of Confucianism. Supposedly, he was a pupil of Confucius' grandson, Zisi. Like Confucius, according to legend, he travelled China for forty years to offer advice to rulers for reform. During the Warring States Period (403–221 BCE), Mencius served as an official and scholar at the Jixia Academy in the State of Qi (1046 BCE to 221 BCE) from 319 to 312 BCE. He expressed his filial devotion when he took an absence of three years from his official duties for Qi to mourn his mother's death. Disappointed at his failure to effect changes in his contemporary world, he retired from public life. Mencius is buried in the "Mencius Cemetery" (孟子林, Mengzi Lin, also known as 亚圣林, Yasheng Lin), which is located 12 km to the northeast of Zoucheng's central urban area. A stele carried by a giant stone tortoise and crowned with dragons stands in front of his grave.

Sun Tzu (孫子; pinyin: Sūnzǐ) is a honorific title bestowed upon Sūn Wu (孫武 c. 544-496 BC), the author of The Art of War (孫子兵法), an immensely influential ancient Chinese book on military strategy. Sun Tzu believed in the use of the military sciences to effect outcomes that would result in peace. In the author's name, Sūn Wu, the character wu, meaning "military", is the same as the character in wu shu, or martial art. Sun Wu also has a courtesy name, Chang Qing (Cháng Qīng).
