拐弯。

Use it simply when giving directions. Just say 在这里拐弯 (Turn here). You can also add directions like 向左拐弯 (Turn left). When talking about people, say someone's brain 不会拐弯. This means they are very literal or rigid thinkers. It’s like their thoughts are stuck on a one-way highway with no exits.

You’ll use this constantly in a taxi or Didi. It's essential for navigating any Chinese city. Use it when explaining a complex idea to see if someone 'gets' it. It’s perfect for casual chats about personality types too. If a friend is being stubborn, tell them to 转个弯 (turn a bit).

Don't use it for 'turning' a page in a book; that's 翻页. Avoid using it for 'turning' into a different person or object. In very formal business contracts, you might use 转弯 or more technical terms. If you are literally spinning in circles, use 转圈 instead. Don't use the mental version to insult your boss unless you want a very short career.

Chinese culture often values 'roundness' and flexibility. Being too 'straight' (直) can sometimes be seen as being blunt or rude. 拐弯 represents the social art of being indirect to save face. Historically, Chinese alleys (hutongs) are full of sharp turns. Navigating these required literal and social agility. Today, it’s a staple of modern urban life and office slang.

You will often hear 拐个弯 (turn a corner). People also say 转弯 which is almost identical but feels slightly more formal. In Northern China, you might hear 绕弯子 (going around in circles). This usually means someone is avoiding the main point. If someone is 'straight-brained,' they are 脑筋不转弯.
