Chinese grammar语法: Expressing as one likes with 就jiu

When we want to express "to do something as one pleases", we can use the "想 + verb +就 + verb" form in Chinese grammar.

Basic Structure

This structure is similar to how we would say in English "Whatever I want to eat, I eat" or "wherver I want to go, I go". What comes after the 想 and 就 are the same verb.

想+verb（+object）+就+verb（+object）

Examples 

Nǐ xiǎnɡ lái jiù lái.
你想来就来。

If you want to come, come.

Structure with a question word

You can also add in a question word, like 什么, 哪儿, or 怎么. When this is the case, the pronouns don't necessarily refer to any specific thing. They can be seen more as words like "whatever" or "wherver". This way, question pronouns (什么,谁,什么时候,etc) serve as "indefinite references".

Xiǎnɡ qù nǎ ér jiù qù nǎ.
想去哪儿就去哪。

wherver you want to go, go there.
