殡仪 is a formal term for funeral rites or the funeral service itself. In everyday speech, people more often say 葬礼 (zànglǐ), but 殡仪 appears in official and institutional contexts, especially in compounds like 殡仪馆 (bìnyíguǎn, funeral home) and 殡仪服务 (bìnyí fúwù, funeral service). If you look up 'funeral' in a dictionary, you'll likely find 葬礼 first — 殡仪 is the more elevated, somewhat bureaucratic variant.
