Mencius was a Chinese philosopher and was arguably the most famous Confucian after Confucius himself.
Life
Mencius, also known by his birth name Meng Ke or Ko, 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.[6] 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.

Mencius' mother
Mencius' mother is often held up as an exemplary female figure in Chinese culture. One of the most famous traditional Chinese four-character idioms is 孟母三遷 (mèng mǔ sān qiān; literal translation: "Mencius' mother, three moves").
This saying refers to the legend that Mencius' mother moved house three times before finding a location that she felt was suitable for the child's upbringing. As an expression, the idiom refers to the importance of finding the proper environment for raising children.
Mencius's father died when he was very young. His mother Zhang (仉) raised her son alone. They were very poor. At first they lived by a cemetery, where the mother found her son imitating the paid mourners in funeral processions. Displeased the mother decided to move. The next house was near a market in the town. There the boy began to imitate the cries of merchants (merchants were despised in early China), so the mother moved to a house next to a school. Inspired by the scholars and students, Mencius began to study. His mother decided to remain, and Mencius became a scholar.
