无论…都【wúlùn … dōu】

无论…都 says the result is the same however an open question turns out. It works exactly like 不管…都, but belongs to writing and formal speech: notices, news, speeches, essays.

The first half has to be a question

The 无论 half needs a question word, a positive-negative pair, or two choices joined by 还是. A plain statement doesn't fit.

• × 无论天气很冷，他都去 → 无论天气多冷，他都去
• × 无论下雨，比赛都进行 → 无论是否下雨，比赛都照常进行

In writing, 是否 often stands in for the positive-negative pair: 无论是否同意, "whether or not they agree".

都 goes after the subject

• × 无论多忙，都他参加 → 无论多忙，他都参加

无论如何

无论如何 is a fixed phrase, "in any case, whatever happens". It stands at the front with no second clause marker needed.
