I found some people call others 老铁. What does this mean? Does it mean friend? I can't find this usage in any dictionaries.
老铁 is a term that originates from Northeastern Mandarin (東北話), and means "bro" or "close friend". Slang from regional dialects often spill over into mainstream Chinese and get adopted by everyone.
老: literally means old, but by adding in front of a pronoun, it produces a sense of intimacy.
老王 (Mr. Wang, but most likely someone you are famaliar with)
铁: literally "iron", describes a strong relationship.
铁哥们 (buddy, has a stronger relationship than "老哥")
巴铁 (some Chinese use this term to describe the relationship between China and Pakistan (巴基斯坦))
Note: The word is an internet slang derived from Dongbei dialect, so of course you can't find any definition in a formal dictionary.
According to baidu
Which also fits with the use of it as far as I have seen it
You can think 老铁 just means "guys" or "buddy" in english
more close than guys.
but a little 调侃
Means Pakistan and China are Iron Brothers. It’s signifies the relationship between the 2 countries.
Welcome to Chinese Language! I'm not sure how Pakistan figures into this ... Oct 3, 2022 at 17:12
