===== Core Meaning =====
  * **Pinyin (with tone marks):** kāi yè chē
  * **Part of Speech:** Verb-Object Phrase
  * **HSK Level:** HSK 4
  * **Concise Definition:** To work or study late into the night.
  * **In a Nutshell:** 开夜车 (kāi yè chē) is a vivid metaphor for staying up all night to accomplish a task, usually for work or school. It paints a picture of someone "driving" their project or study session through the darkness of night to reach their destination (the deadline). It carries a feeling of hard work, sleep deprivation, and pressure.
===== Character Breakdown =====
  * **开 (kāi):** To open; to start; to operate (a vehicle).
  * **夜 (yè):** Night; nighttime.
  * **车 (chē):** Car; vehicle.
The characters literally combine to mean "operate a night car." This metaphor extends the idea of a long-haul driver pushing through the night to get a job done. In the same way, a student or employee "drives" their work through the night to meet a deadline. It's a much more dynamic and descriptive phrase than simply saying "work late."
===== Cultural Context and Significance =====
  * **Cultural Importance:** 开夜车 (kāi yè chē) is deeply embedded in the modern Chinese experience of education and work. It's a rite of passage for almost every student preparing for major exams, especially the notoriously difficult **高考 (gāokǎo)**, the national college entrance examination. The pressure to succeed is immense, and "pulling an all-nighter" is often seen as a necessary sacrifice. In the professional world, particularly within the tech industry's "996 culture" (working 9 am to 9 pm, 6 days a week), 开夜车 is a common, almost expected, part of the job.
  * **Comparison to Western Culture:** The English phrases "pulling an all-nighter" or "burning the midnight oil" are very close equivalents. However, the cultural pressure and frequency associated with 开夜车 in China can be more intense. While an American student might pull an all-nighter for a final exam, the behavior is often seen as a result of poor time management. In China, due to the sheer volume of work and competition, 开夜车 can sometimes be viewed as a sign of diligence and commitment—a demonstration of the cultural value of **吃苦 (chī kǔ)**, or "enduring hardship." It’s a shared experience that bonds students and colleagues.
===== Practical Usage in Modern China =====
  * **Formality:** Highly informal. Used among friends, classmates, and close colleagues. You would not use it in a formal report, but you might say it to your boss in a casual conversation if you have a good relationship.
  * **Connotation:** The connotation is usually a mix of complaint, exhaustion, and sometimes a humble brag about one's diligence. It’s a way of saying "I'm working really hard and I'm tired." It's rarely seen as a purely positive thing because it implies a lack of sleep and a heavy workload.
  * **Contexts:**
    * **Students:** Most common among high school and university students facing exams or project deadlines.
    * **Office Workers:** Used frequently by employees, especially in demanding industries like tech and finance, when trying to finish a project or presentation.
    * **Social Media:** People often post about 开夜车 on WeChat Moments or Weibo to share their struggles or show their dedication, often accompanied by a picture of their desk late at night.

===== Nuances and Common Mistakes =====
  * **开夜车 vs. 熬夜 (áoyè):** This is the most common point of confusion.
    * **开夜车 (kāi yè chē):** Specifically means staying up late **to work or study**. It has a clear goal and implies pressure.
    * **熬夜 (áoyè):** A more general term for "staying up late" or "pulling an all-nighter." You can 熬夜 to watch movies, play games, or chat with friends. It doesn't necessarily involve work.
    * //All instances of 开夜车 are a form of 熬夜, but not all 熬夜 is 开夜车.//
    * **Incorrect:** 我昨晚跟朋友**开夜车**看电影。(Wǒ zuówǎn gēn péngyou **kāi yè chē** kàn diànyǐng.) - //This is wrong. You are not "working" on the movie.//
    * **Correct:** 我昨晚跟朋友**熬夜**看电影。(Wǒ zuówǎn gēn péngyou **áoyè** kàn diànyǐng.)
  * **Literal vs. Metaphorical:** In 99.9% of cases, 开夜车 is used metaphorically. To talk about literally driving a car at night, a speaker would almost always say **晚上开车 (wǎnshang kāichē)** to avoid ambiguity. Using 开夜车 for literal driving is only possible in very specific contexts, like describing the job of a long-haul trucker, but even then, other phrases are more common.
