Please tell me how to translate “into English: 时光未老 Please tell me how to translate into English: 时光未老

See below with respect to "into English." For quotes from poetry that span multiple lines or longer quotes from prose, it's typical to instead set it off as a block quote, instead of an in-line quote with quotation marks. "Please tell me how…" suggests the imperative (giving an order or suggestion). It's possible for it to be used to ask a question, but it's a bit informal, and like I mention below, it doesn't seem elegant in written form to place a question mark after a multi-line (or multi-sentence) quote.

Into English? Into English?

This is fine verbally, but written I would move "into English" to right after "translate," to avoid having a sentence split by a large quote in the middle of it.
