'生意' (shēng yì) literally combines 'shēng' (to live, to be born) and 'yì' (meaning, intention, idea), evoking the notion of 'life-giving activity' or 'purposeful endeavor.' Historically, it referred to the flow of vitality or opportunity in commerce — hence its modern primary meaning: 'business' as an economic activity or enterprise. It commonly describes a company’s operations, trade volume, or commercial viability (e.g., '生意很好' means 'business is booming').

The term can also mean 'deal' or 'transaction,' especially in informal spoken contexts ('这单生意我们接了' — 'We’ll take this deal'). Unlike formal terms like '企业' (qǐyè, 'enterprise') or '公司' (gōngsī, 'company'), '生意' carries a practical, everyday tone — often used by small business owners, vendors, or in casual negotiations. It rarely refers to abstract concepts like 'career' or 'profession'; those are better expressed with words like '职业' or '工作.'
