不论 + Condition, 都/也 + Result
不论 functions the same as 不管, meaning "no matter" or "regardless of," but carries a slightly more formal or written tone. It introduces a variable condition while the main clause states an unchanged outcome, usually marked with 都 or 也. It is common in written Chinese and formal speech.

bùlùn shì shéi, dōu bìxū zūnshǒu zhè tiáo guīdìng.
No matter who it is, everyone must follow this rule.
不论走到哪里,他都忘不了家乡的味道。
bùlùn zǒu dào nǎlǐ, tā dōu wàng bù liǎo jiāxiāng de wèidào.
No matter where he goes, he can never forget the flavors of his hometown.
