• Pinyin (with tone marks): tōngchàng
• Part of Speech: Adjective
• HSK Level: HSK 5
• Concise Definition: Free from blockage or obstruction; allowing smooth and unimpeded passage.
• In a Nutshell: 通畅 (tōngchàng) describes the state of something being open and allowing things to pass through it without any hindrance. Think of a perfectly clear highway with no traffic jams, a clean pipe where water flows freely, or a logical argument that's easy to follow. It’s the feeling of “flow” without any obstacles.

• 通 (tōng): This character means “to pass through,” “to connect,” or “to open.” Its radical 辶 (chuò) is related to walking, which reinforces the idea of movement from one point to another. It's the “go-through” part of the word.
• 畅 (chàng): This character means “smooth,” “unimpeded,” or “fluent.” It evokes a feeling of ease and effortless flow.
• Together, 通 (tōng) + 畅 (chàng) literally means “to pass through smoothly.” The combination creates a vivid and versatile adjective that describes any channel, path, or system that is open and working as it should be.

The concept of 通畅 (tōngchàng) is deeply embedded in Chinese culture, particularly in health and philosophy. In Traditional Chinese Medicine (TCM), the smooth flow of 气 (qì), or vital energy, and blood through the body's meridians is the foundation of good health. A doctor might say your 血脉通畅 (xuèmài tōngchàng), meaning your blood circulation is good. Any blockage (不通, bù tōng) is seen as the root of illness. This contrasts with the Western mechanical view of the body, placing more emphasis on holistic flow and balance. Similarly, in Feng Shui (风水), the goal is to arrange living spaces to ensure the 通畅 flow of energy, promoting harmony and good fortune. A cluttered hallway or a poorly placed door would be seen as disrupting this flow. Therefore, 通畅 is not just a physical description; it's a desirable state of being, representing health, harmony, and efficiency.

通畅 (tōngchàng) is a common and practical word used in a wide variety of contexts, from the literal to the highly metaphorical.

• Physical Flow: This is the most common usage. It can describe traffic, pipes, rivers, and even bodily functions.
  • Traffic: 交通通畅 (jiāotōng tōngchàng) - Traffic is smooth.

A common point of confusion for learners is the difference between 通畅 (tōngchàng) and 顺利 (shùnlì). They can both be translated as “smooth,” but they are not interchangeable.

• 通畅 (tōngchàng): Describes a channel or path being free of blockages. It focuses on the condition of the path.
  • Correct: 道路很通畅。 (Dàolù hěn tōngchàng.) - The road is unobstructed.
  • Incorrect: 我的会议很通畅。 (Wǒ de huìyì hěn tōngchàng.)
• 顺利 (shùnlì): Describes a process or event proceeding without problems or difficulties. It focuses on the outcome of an action.
  • Correct: 会议进行得很顺利。 (Huìyì jìnxíng de hěn shùnlì.) - The meeting went smoothly.
  • Incorrect: 道路很顺利。 (Dàolù hěn shùnlì.)

Mistake to Avoid: Don't use 通畅 to describe a project, a meeting, or an exam. These are processes, not channels. Use 顺利 instead. Think of it this way: a 通畅 road helps you have a 顺利 journey.

• 堵塞 (dǔsè) - To be blocked; congested. The direct antonym of 通畅.
• 流畅 (liúchàng) - Fluent; smooth. Very similar to 通畅 but used almost exclusively for speech, writing, or performance (e.g., speaking fluent Chinese: 中文说得很流畅).
• 顺利 (shùnlì) - Smoothly; successfully. Describes a process or event, not a physical channel.
• 畅通无阻 (chàng tōng wú zǔ) - An idiom meaning “completely unhindered and unobstructed.” It's a more emphatic and formal version of 通畅.
• 疏通 (shūtōng) - To dredge; to unblock. This is the verb for the action of making something 通畅.
• 交通 (jiāotōng) - Traffic; transportation. The thing that is often described as being 通畅 or 堵塞.
• 清晰 (qīngxī) - Clear; distinct. Can be used for vision, sound, or abstractly for logic (思路清晰), overlapping with the “clear thoughts” meaning of 通畅.
• 气 (qì) - Vital energy. The concept of its smooth flow (气血通畅) is a core cultural idea related to 通畅.
