At the end of his secondary schooling at Lycée Quốc học, the French lycée in Huế, Diem's outstanding examination results elicited the offer of a scholarship to study in Paris. He declined and, in 1918, enrolled at the prestigious School of Public Administration and Law in Hanoi, a French school that prepared young Vietnamese to serve in the colonial administration. It was there that he had the only romantic relationship of his life, when he fell in love with one of his teacher's daughters. After she chose to persist with her vocation, entering a convent, he remained celibate for the rest of his life. Diệm's family background and education, especially Catholicism and Confucianism, had influences on his life and career, on his thinking on politics, society, and history. According to Miller, Diệm "displayed Christian piety in everything from his devotional practices to his habit of inserting references to the Bible into his speeches"; he also enjoyed showing off his knowledge of classical Chinese texts.
