===== Core Meaning =====
  * **Pinyin (with tone marks):** kāitōng
  * **Part of Speech:** Verb
  * **HSK Level:** HSK 4
  * **Concise Definition:** To open, inaugurate, or establish a service, route, or connection.
  * **In a Nutshell:** **开通 (kāitōng)** is about creating a new, functional pathway where one didn't exist before. Think of it as "opening a channel." This channel can be literal, like a new high-speed rail line connecting two cities, or it can be a service, like activating a data plan on your phone. It's the action of making something accessible and operational for the first time.
===== Character Breakdown =====
  * **开 (kāi):** To open, to start, to turn on. The character resembles a gate or door (门) with the latch (一) being lifted. It signifies the basic action of opening.
  * **通 (tōng):** To go through, to connect, to be unobstructed. This character suggests a clear passage or a connection from one point to another.
  * When combined, **开通 (kāitōng)** literally means "to open a connection" or "to start a passage." This perfectly captures its meaning of establishing a new, functional link, whether it's for transportation, communication, or services.
===== Cultural Context and Significance =====
  * **开通** is a word you'll hear constantly in modern China, as it is inextricably linked to the country's rapid development. Every time a new subway line is completed, a new bullet train route is launched, or a bridge connects two regions, the verb used to announce it is **开通**. It is the sound of progress and increasing connectivity.
  * In the digital sphere, it's just as crucial. From opening an Alipay account (`开通支付宝`) to activating a streaming membership (`开通会员`), **开通** is the key that unlocks participation in China's vibrant digital economy.
  * **Comparison to Western Concepts:** In English, we use different verbs for these situations: "open" an account, "launch" a service, "inaugurate" a railway. **开通** elegantly bundles these concepts into one, unified by the core idea of "establishing a new, functional connection." While "to open" in English can be as simple as opening a jar, **开通** is reserved for systems, services, and infrastructure, giving it a more significant and formal weight.
