More than just a specific phrase, it describes the social //action// of acknowledging someone's presence, which can range from a simple nod or wave to a formal verbal greeting. Understanding how and when to //打招呼// is key to navigating Chinese social etiquette.

===== Core Meaning =====
  * **Pinyin (with tone marks):** dǎ zhāohu
  * **Part of Speech:** Verb-Object Phrase (often functions as a separable verb)
  * **HSK Level:** HSK 3
  * **Concise Definition:** To greet someone or to notify someone in advance.
  * **In a Nutshell:** //打招呼 (dǎ zhāohu)// isn't the greeting itself, but the //act// of greeting. You don't say "dǎ zhāohu!" to someone. Instead, you use it to talk //about// greeting. For example, you can say, "I saw my teacher and greeted her." It's the "greeted" part that is //打招呼//. It emphasizes the social ritual of acknowledgement, which is a cornerstone of politeness in Chinese culture.
===== Character Breakdown =====
  * **打 (dǎ):** While its most common meaning is "to hit" or "to strike," here it functions as a highly versatile verb prefix indicating "to perform an action." Think of it like "to make" or "to do" in phrases like `打电话 (dǎ diànhuà)` (to make a phone call) or `打车 (dǎ chē)` (to hail a taxi).
  * **招 (zhāo):** This character means "to beckon" or "to wave," often with the hand. It contains the hand radical (扌).
  * **呼 (hū):** This character means "to call out" or "to shout." It contains the mouth radical (口).
The characters combine to create a vivid image: performing the action (打) of waving with your hand (招) and calling out with your mouth (呼). This perfectly encapsulates the physical and verbal act of greeting someone.
===== Cultural Context and Significance =====
In Chinese culture, //打招呼// is more than just a casual pleasantry; it's a fundamental act of maintaining social harmony and showing respect. It's the glue that holds daily interactions together in communities, neighborhoods, and workplaces.
Compared to the Western concept of "saying hi," which is often optional, consistently failing to //打招呼// to acquaintances in China can be interpreted as being arrogant, rude, or even having a problem with that person. It's a small but constant way to acknowledge a person's presence and affirm your shared social space. This is especially important when interacting with elders, teachers, or superiors, where a timely greeting is a sign of proper upbringing and respect. The act reinforces [[关系]] (guānxi) by demonstrating that you see and value the other person.
===== Practical Usage in Modern China =====
//打招呼// is used in countless daily situations, and its form changes depending on the context and formality.
  * **As "To Greet":** This is its primary and most common meaning. It can be verbal or non-verbal.
    *   **Informal:** Seeing a neighbor in the hallway, you might nod and say "吃了没?" (chī le méi? - Have you eaten?) or simply "嗨" (hāi). This action is //打招呼//.
    *   **Formal:** At a business meeting, you would //打招呼// by shaking hands, bowing slightly, and saying "你好" (nǐ hǎo) while exchanging business cards.
  * **As "To Give a Heads-up" / "To Notify":** This is a very common secondary meaning that often confuses learners. It means to inform someone of something in advance, usually as a courtesy.
    *   If you're planning to leave a party early, you should "跟主人打个招呼" (gēn zhǔrén dǎ ge zhāohu) — "let the host know" before you slip out.
    *   If a manager is going to implement a new policy, they might //打招呼// with the team beforehand to prepare them for the change.

===== Nuances and Common Mistakes =====
  * **Mistake 1: Using it //as// a greeting.**
    * A beginner might walk up to someone and say, "**打招呼**!" This is incorrect. It's like walking up to someone in English and saying "To greet!"
    * **Incorrect:** (To a person) **打招呼**！
    * **Correct:** (To a person) 你好！(Nǐ hǎo!) or 嗨！(Hāi!)
    * **Correct Usage:** (Talking //about// the action) 我刚才跟他**打招呼**了。(Wǒ gāngcái gēn tā dǎ zhāohu le.) - "I just greeted him."
  * **Mistake 2: Confusing //打招呼 (dǎ zhāohu)// with //问好 (wènhǎo)//.**
    * While both relate to greeting, they are not interchangeable.
    * **打招呼 (dǎ zhāohu)** is a direct greeting you give to someone you see in person (verbally or non-verbally).
    * **问好 (wènhǎo)** means "to send regards" or "to ask after someone's well-being" on behalf of yourself or someone else. You use it when the person is //not// present.
    * **Example:** 请替我向你父母**问好**。(Qǐng tì wǒ xiàng nǐ fùmǔ **wènhǎo**.) - "Please send my regards to your parents." You would never say "替我向你父母打招呼".
