• Pinyin (with tone marks): nèiháng
• Part of Speech: Noun, Adjective
• HSK Level: HSK 4
• Concise Definition: An expert or professional; to be skilled and knowledgeable in a particular trade or field.
• In a Nutshell: 内行 (nèiháng) literally translates to “inside the trade.” It describes someone who possesses deep, practical, and often hands-on knowledge of a specific subject, craft, or business. This isn't just about book smarts; it's about being “in the know.” Think of the person who can spot a fake antique, taste the subtle notes in tea, or immediately identify a bug in a line of code. They are a 内行.

• 内 (nèi): This character means “inside,” “inner,” or “internal.” It's found in words like 内部 (nèibù, internal) and 内容 (nèiróng, content).
• 行 (háng): While this character can also be pronounced `xíng` (to walk, to go), here it's pronounced `háng` and means “a trade,” “a profession,” or “a field of business.” Think of a “row” of businesses in the same industry, like 银行 (yínháng, bank) or 行业 (hángyè, industry/trade).

When combined, 内行 (nèiháng) creates the vivid image of someone who is “inside the profession,” an insider with privileged knowledge and experience that an outsider, or a 外行 (wàiháng), lacks.

In Chinese culture, there's a profound respect for earned, practical expertise. 内行 (nèiháng) captures this value perfectly. It often implies knowledge gained through years of experience and deep involvement, not just from passing an exam or earning a degree. A good Western comparison is the difference between an “expert” and a “pro” or someone who “knows their stuff.” While “expert” can sound academic and formal (closer to the Chinese term 专家 (zhuānjiā)), 内行 (nèiháng) feels more grounded and practical. It’s the difference between a food critic who writes about restaurants and a chef who instinctively knows how to balance flavors. The chef is the 内行. This term highlights a cultural appreciation for substance over superficiality. A true 内行 can see past the surface to the “knack” or the “trick of the trade,” a concept known as 门道 (méndào). The opposite, a 外行 (wàiháng), can only see the superficial excitement or appearance (热闹 rènao). This is captured in the popular saying: 内行看门道，外行看热闹 (Nèiháng kàn méndào, wàiháng kàn rènao) — “The expert sees the technique, the layman just sees the spectacle.”

内行 (nèiháng) is an extremely common word used in daily conversation, business, and online forums.

  • Pinyin: Tā zhuāngzuò hěn nèiháng de yàngzi, jiéguǒ jǐ jù huà jiù lòuxiàn le.
  • English: He pretended to be an expert, but he was exposed after just a few sentences.
  • Analysis: `露馅 (lòuxiàn)` means “to let the cat out of the bag” or “to be exposed.” This shows that you can't easily fake being a 内行.
• Example 10:
  • 内行看门道，外行看热闹。
  • Pinyin: Nèiháng kàn méndào, wàiháng kàn rènao.
  • English: The expert looks for the technique, while the layman just enjoys the show.

• 内行 (nèiháng) vs. 专家 (zhuānjiā): This is the most common point of confusion.
  • 内行 (nèiháng): Implies practical, hands-on, experience-based expertise. It's more about “know-how.” A great car mechanic, a skilled chef, or a savvy stock trader is a 内行.
  • 专家 (zhuānjiā): Implies formal, often academic or scientific, expertise. It's more about “know-what.” A university professor, a research scientist, or a medical specialist is a 专家.
  • While there is overlap, you wouldn't typically call a professor a 内行 in their academic field (you'd use 专家), and you wouldn't usually call a master carpenter a 专家 (you'd use 内行 or 高手 gāoshǒu).
• Incorrect Usage: Don't use 内行 for general knowledge or skills that don't belong to a specific “trade” or “field.”
  • Incorrect: `他在睡觉方面很内行。` (He is an expert at sleeping.)
  • Why it's wrong: Sleeping is a universal human activity, not a specialized profession or craft (`行 háng`). The term loses its meaning here. It must apply to a domain where one can have insider knowledge.

• 外行 (wàiháng) - The direct antonym of 内行. It means “layman,” “amateur,” or “outsider.”
• 专家 (zhuānjiā) - A more formal term for “expert,” usually referring to someone with academic or official credentials.
• 高手 (gāoshǒu) - “High hand.” A master of a particular skill, often used for martial arts, video games, sports, or a craft. It overlaps with 内行 but emphasizes a high level of performance.
• 老手 (lǎoshǒu) - “Old hand.” A veteran; someone who is very experienced at something through long practice.
• 门道 (méndào) - “Door way.” The key to success, the “ins and outs,” the trick of the trade. This is what a 内行 understands.
• 在行 (zàiháng) - A verb meaning “to be skilled at,” “to be an expert in.” It's very similar to using 内行 as an adjective. `他做饭很在行。` (He is very skilled at cooking.)
• 专业 (zhuānyè) - Professional; a major of study. As an adjective, it means “professional” and emphasizes a high standard of quality. `他做事很专业。` (He does things very professionally.)
