Here's a cool idiom I learned this week.

"An abrupt end" (戛然而止 jiá rán ér zhǐ)

This one comes from a literary criticism text:

Comprehensive Meaning of Literature and History (文史通义), written by Zhang Xuecheng (章学诚), a historian and philosopher of the Qing Dynasty.

In a chapter titled Ten Flaws of Classical Prose (古文十弊), Zhang writes:

"Great writing follows a path as mysterious and masterful as those of the gods. It arrives like a sudden bolt of lightning, and it ceases with an abrupt, sharp silence."

夫文章变化，侔于鬼神，斗然而来，戛然而止，何尝无此景象？

Zhang's point:

The most powerful prose keeps a reader off balance — arriving suddenly, and cutting out just as sharply.

In plain English: something stops mid-flow, without warning.

In modern Chinese, it describes anything that ends abruptly — a conversation, a piece of music, a career, a life.

Example:

The music stopped dead — no fade, no warning, nothing. 音乐戛然而止，没有任何预兆。
