If people, a family, a shop, or a country prosper, they grow and do well over time, especially by making money or a good profit. It is about a stretch of years, not one lucky day: a café that is packed on Saturday has not prospered yet; a café that is still growing five years later has.

If people, a family, a shop, or a country prosper如果人、家庭、商店，或是一個國家 prosper（興旺）, they grow and do well over time就表示他們隨著時間成長、發展得很好, especially by making money or a good profit特別是靠賺錢或得到不錯的利潤。It is about它指的是 a stretch of years一段很長的時間, not one lucky day不是某一天運氣好: a café that is packed on Saturday一家星期六客滿的咖啡店 has not prospered yet還不算 prosper; a café that is still growing five years later一家五年後還在持續成長的咖啡店 has才算是 prosper。

You hear it in news about the economy, in speeches, and in wishes (“I hope you prosper”), so it feels a little more formal than “do well” — though actually it is not stiff or rare. Money is usually part of the meaning, but people also use it when a farm or a town stays healthy and strong, not only when someone becomes rich.

You你 hear it會聽到它 in news about the economy在經濟新聞裡, in speeches演講裡, and in wishes還有祝福語裡 ("I hope you prosper")（「I hope you prosper」）, so it feels所以感覺 a little more formal than "do well"比「do well」正式一點 — though actually不過其實 it is not stiff or rare它並不生硬，也不算罕見。Money錢 is usually part of the meaning通常是這個字意思的一部分, but people also use it但大家也會用它 when a farm or a town stays healthy and strong在農場或城鎮維持健康強盛的時候, not only when someone becomes rich不只是有人變有錢的時候。
