外行

• Pinyin: wài háng
• Hanzi breakdown: 外 = 夕 (evening) + 卜 (divination); 行 = pictograph of a crossroads — extended to mean 'walk, profession, trade'

Meaning

Layperson; amateur; outsider. Someone who lacks expertise or professional training in a particular field.

Functions as both a noun (a layperson) and an adjective (amateurish, out of one's depth). The antonym is 内行 (nèiháng), an expert or insider. Often used in self-deprecating speech (我是外行) or as pointed criticism (外行领导内行 — amateurs managing experts). The proverb 外行看热闹，内行看门道 ('outsiders watch the spectacle, insiders see the craft') is widely quoted.

Examples

1. 他是做金融的，对农业完全是个外行，但这并不妨碍他提出一些新奇的见解。 He works in finance and is a complete outsider when it comes to agriculture, but that doesn't stop him from coming up with some novel ideas.
2. 外行领导内行是很多企业管理中长期存在的痼疾，往往导致决策失误。 Amateurs managing experts is a chronic problem in many companies, often leading to poor decision-making.
3. 我对古典音乐是十足的外行，只是单纯地喜欢听，说不出什么门道来。 I'm a total layperson when it comes to classical music — I simply enjoy listening and can't explain the craft.
