(Ivory Tower) According to the fourth quarter of Chapter 7 of the Song of Songs in the Old Testament, Solomon, the wise and rich king of Israel, wrote 1005 poems, among which the Song of Songs is a song of love. In the fifth song, the groom praised the bride like this: "... your neck is like an ivory tower. Your eyes are near the gate of Bartrabbi in Heshbon, like a pool ... (... your neck is like an ivory tower; Your eyes are like a pool near the sliding door of Heshbon Patna; ……)。 Obviously, the ivory tower here is only used to describe the bride's beautiful neck. Later, the word was gradually applied to all aspects of social life, mainly referring to "an isolated fantasy, a paradise to escape from real life, and an isolated place". In Chinese, the extended meaning of ivory tower mainly refers to "the metaphor of the small world of writers and artists who are divorced from real life". Universities and research institutes are such places.

The ivory tower is just a concept, which people use in their lives to illustrate the unreality of life.

University life is beautiful, and it is also a place that many people yearn for, but after all, it is just the imagination of people who have never been here.
