How it's used

While often used for the eldest sibling, this term carries a strong connotation of authority or seniority in a social or professional hierarchy. When applied to someone outside the family, it can sound slightly informal or even imply a connection to underworld figures depending on the context. Using it to address a stranger in a professional setting can come across as overly familiar or cheeky.

Common phrases

to act as the leader

Common mistake

Do not confuse this with 大佬, which is much more commonly used in Hong Kong to refer to a big brother figure or a gang leader. Using 老大 in casual conversation might sound like you are mimicking Mandarin or watching too many crime movies.
