Nguyễn Bỉnh Khiêm (chữ Hán: 阮秉謙; 1491–1585) was a Vietnamese administrator, confucianist, poet, prophet and later a saint of the Cao Dai religion and of the new religious movement known as School of Teaching Goodness.

As an adult, he studied knowledge from the second-rank doctor Lương Đắc Bằng and passed the official government examination at the fairly late age of 44 in the exams of 1535.

Among his students were Phùng Khắc Khoan (diplomat), Lương Hữu Khánh, Nguyễn Dữ (author of Truyền kỳ mạn lục).

[5] The School of Teaching Goodness emerged in the 1990s in the Vĩnh Bảo District, a rural area of the city of Hải Phòng.

A local carpenter known simply as "Master Thu" claimed to have been visited at night by the spirit of Khiêm, who ordered him to build a shrine in his honor.

Thu owned some land, where he built and inaugurated in 1996 a shrine he called Minh Đường Trung Tân (The School of Teaching Goodness).
