老板 (lǎo bǎn) literally combines 老 (lǎo, 'old' or 'senior') and 板 (bǎn, originally meaning 'board' or 'plank', but here used phonetically). Historically, it referred to the person in charge of a shop’s wooden counter or signboard — the one who 'owned the board'. Today, it’s a widely used, informal term for the owner or manager of a business, especially small- to medium-sized shops, restaurants, or private companies. It conveys respect and familiarity, not age.

Unlike formal titles like 总经理 (zǒng jīng lǐ, 'general manager'), 老板 is warm, colloquial, and common in daily spoken Mandarin. You’ll hear it addressed directly ('Lǎo bǎn, zhè ge zěnme mǎi?'), used when referring to someone else ('Tā shì wǒmen diàn de lǎo bǎn'), or even jokingly among peers. It’s rarely used for high-level corporate executives in official contexts, where titles like 董事长 (dǒng shì zhǎng) are preferred.
