惠顾 (huì gù) is a formal, respectful verb used primarily in business contexts to express gratitude for a customer’s patronage. Literally, 惠 (huì) means 'favor' or 'grace', and 顾 (gù) means 'to visit' or 'to attend to'; together, they convey the idea of 'graciously visiting (and thus supporting) a shop or service'. It carries strong connotations of humility and courtesy — the speaker (often a shopkeeper or staff member) positions themselves as honored by the customer’s presence.

This term is rarely used in casual speech or among peers; instead, it appears in storefront signs ('欢迎惠顾'), receipts, announcements, and polite verbal greetings when welcoming customers. It is almost always used in the passive or appreciative voice — never to describe one’s own action of shopping ('I will patronize the store') — and typically follows verbs like 欢迎 (welcome) or expresses thanks after a transaction.
