Trạng Trình: How Political Advice Became Prophecy
In 1535, Nguyễn Bỉnh Khiêm passed the highest imperial examination in the Mạc court at the age of forty-four. He had been born in 1491 in Trung Am, in what is now Vĩnh Bảo, Hải Phòng. He served for about eight years, then submitted a memorial asking the court to punish eighteen powerful officials. The king refused. Khiêm left office, returned home, opened the Bạch Vân school, and still received visitors from rival power blocs.
