The Minister of Education attended the opening ceremony.
Tips
usage
Built from 教育部 (Ministry of Education) + 长 (head). The same -部长 suffix names the head of any ministry: 外交部长 (Foreign Minister), 国防部长 (Defense Minister), 财政部长 (Finance Minister).
mistakes
长 here is zhǎng (head of, leader) — not cháng (long). The reading shift is reliable in titles: 部长, 校长, 院长, 队长 are all -zhǎng.
