不管…都【bùguǎn … dōu】

不管…都 says the result is the same however an open question turns out. The 不管 half holds the open question; 都 (or 也) goes before the verb of the result, after its subject. It is the everyday spoken form.

The first half has to be a question

What follows 不管 has to leave something open. There are three ways to do that:

• a question word: 谁, 什么, 怎么, 多, 哪儿, 什么时候
• a positive-negative pair: 去不去, 贵不贵
• two choices with 还是: 你去还是我去

A plain statement after 不管 is the mistake learners make most.

• × 不管下雨，我都去 → 不管下不下雨，我都去
• × 不管很贵，我都买 → 不管多贵，我都买

都 goes after the subject

• × 不管多晚，都我等你 → 不管多晚，我都等你

多 + adjective is the way to say "however": 不管多忙, "however busy". 无论…都 means the same and is more formal; it has its own point.
